Best Online Stock Trading Brokers for 2018 If you’re looking for a way to build more wealth in 2018, getting started with one of the best online brokerage accounts is a solid first step. Doing so will allow you to invest outside your traditional retirement accounts and on your own terms. The best part is, the best online brokerage firms charge little or no fees and offer excellent resources that can help you learn more about investing along the way. Of course, not all brokerage firms are created equal, and that’s why we took the time to break down each of their details and rank the top options on an array of factors. If you’re looking for a new way to invest this year and are ready to strike out on your own, the following online brokerage accounts should be at the top of your list.What Matters When You Trade Stocks on Your Own? Managing your own money can be a stressful endeavor. To minimize this, and to minimize information overload that tends to come from watching the markets 24/7, there are a few must-haves to look for in an online broker. Clean interface. When I trade, I want to be able to easily find my order entry ticket. I don’t want it buried under a number of drop downs. This interface should have intuitive access to see your balance, available cash, positions with real time P/L and all be easily navigated. Quick access to basic charting. A chart tells me where the stock has been recently. I don’t trade minute to minute anymore, so I don’t need complex tools like stochastics or retracement lines. All that’s important is that I have a basic chart on a yearly, monthly, weekly, daily and intra day time period. I use a chart to see current price relative to those time periods, mainly to avoid purchasing at a bad price. Low fees. One of the biggest roadblocks to building wealth is fees incurred to invest your hard-earned dollars. Because the fees charged by different brokerage firms vary so dramatically, it’s crucial to seek out options that charge low fees (or no fees) for account management and trades. There are over 50 online brokerages where you can open an account. Beyond the my three rules above, best online brokerage accounts aren’t just for trading stocks. Sure, many of them started as online stock trading accounts, but now they’re full-fledged trading, saving, investing, retirement planning, and banking machines. This industry is more complex than the average person thinks. You shouldn’t just pick any online broker and sign up for an account. The best online broker for one person is often completely different for the next person. Use this resource as a guide to your decision process. Figure out what features are best for you, and make your selection. What Makes a Great Online Broker? I analyzed a number of elements to come to my decision on which brokers are the best. Later in this post, I provide full details on how I selected the best online brokerages. When you take all the features, resources, trading platforms, and technology into account (while also considering every type of trader), the full-service brokers, like E*TRADE and TD Ameritrade are the best for the largest number of people. For those simply looking to make cheap trades, I would recommend going with Optionshouse. If you’re a very advanced trader, high-volume trader, or a professional who manages money, I recommend going with Interactive Brokers. However, I didn’t include Interactive Brokers on my list because they’re best for a very small group of traders and the platform is very complex. Top Qualities of Standout Online Trading Platforms Quality trading tools and technology Multiple trading platforms for all levels of traders Excellent mobile trading features Solid navigation that displays the relevant information where you want it Quality educational resources and research for trader development There’s more to selecting an online broker than price. You have to consider the resources you’re getting for the cost you pay per trade. For example, my colleague, who is also an ex-trader, likes to use a combination of stock and options trade in his longer-term trading. He recently switched over to Fidelity because he really liked the cash management features, but was very disappointed by complex order entry, sub-par options execution and frustrating navigation. He’s currently making the switch to one of the brokers I profile here.

Penerapan Gaya Sentripetal Pada Atraksi Tong Setan

Jika kau pernah mengunjungi pasar malam niscaya pernah melihat atraksi pengendara motor dengan lihai mengitari tong tanpa sekalipun terjatuh. Atraksi ini sering disebut dengan istilah tong edan. Di katakan tong edan alasannya ialah atraksi ini cukup asing (edan), tidak semua orang sanggup melaksanakan atraksi ini. Nyali kita benar-benar diuji dalam memainkan atraksi ini. Selain itu atraksi ini juga sering disebut dengan istilah tong setan, alasannya ialah banyak yang mempercayai bahwa atraksi ini dilakukan alasannya ialah pengemudi sepeda motor tersebut mempunyai ilmu magic (mistis). Ada juga yang menyebut atraksi ini dengan nama roda-roda asing dan tong stand.

Tong edan merupakan atraksi ketrampilan mengemudikan sepeda motor atau sepeda gayung di dalam sebuah tong berbentuk tabung yang umumya berdiameter 8-9 meter dan mempunyai kemiringan sekitar 70-90 derajat. Di dalam tong inilah pemain memacu kendaraannya. Tahukah kau dalam atraksi tong edan ini ternyata ada teori fisika dan tidak ada ilmu mistisnya. Pengendara dalam atraksi tong edan ini menerapkan atau mengaplikasikan konsep gaya sentripetal semoga kondusif dalam melaksanakan atraksi ini. Bagaiamana penerapan gaya sentripetal pada atraksi tong edan?

Sekarang perhatikan gambar atau ilustrasi dari sepeda motor yang berjalan di dalam tong edan dibawah ini.
Jika kau pernah mengunjungi pasar malam niscaya pernah melihat atraksi pengendara motor den Penerapan Gaya Sentripetal Pada Atraksi Tong Setan

Ketika sepeda motor bergerak di dinding tong (tabung) ada sejumlah gaya yang bekerja. Gaya berat w yang mengarah ke bawah, gaya gesek fs yang bersinggungan eksklusif dengan ban sepeda dan berlawanan arah dengan gaya berat, dan juga gaya sentripetal Fs yang sama dengan gaya Normal (N) yang mengarah ke sentra lingkaran.

Sepeda motor tidak terjatuh dikarenakan gaya gesek dan gaya berat menyeimbangkan satu sama lain. Singkatnya, dua gaya ini bertindak dalam arah yang berlawanan dan bertanggung jawab satu sama lain. Gaya-gaya pada arah vertikal seimbang sehingga berlaku persamaan berikut ini.
fs = w
μs . N = m.g
N =m.g/μs

Agar sepeda motor tetap melaju dilintasannya, harus ada kelajuan minimum dari sepeda motor.  Kelajuan ini akan menghasilkan gaya setripetal. Gaya sentripetal ini sama dengan gaya normal yang menarah ke sentra bulat juga. Gaya normal ini akan mengakibatkan timbulnya gaya gesek antara ban dan dinding tong. Semakin besar kelajuan sepeda motor maka gaya sentripetalnya makin besar dan tentunya gaya gesek yang dihasilkan akan bertambah juga. Ini sangat penting alasannya ialah kalau gaya berat lebih besar daripada gaya gesek, maka sepeda motor akan meluncur ke bawah dan pengendara akan jatuh. Berapa kelajuan minimum sepeda motor semoga sanggup tetap bergerak di dinding tong edan tanpa terjatuh?

Seperti yang dijelaskan di atas bahwa gaya sentripetal sama dengan gaya normal (N) sehingga:
Fs = N
mv2/R = m.g/μs
v2/R = g/μs
v2 = gR/μs

Keterangan:
v = kelajuan minimum
R = jari-jari tikungan yang berbentuk bulat
g = percepatan gravitasi
μs = tabrakan statis

Jadi, dari persamaan v2 = gR/μs  sanggup disimpulkan bahwa semoga sepeda motor tidak jatuh, semakin besar jari-jari atau diameter tong (tabung) maka kecepatan minimum yang diharapkan makin besar.


Untuk memantapkan pemahaman kau wacana penerapan gaya sentripetal pada tong edan, silahkan simak pola soal di bawah ini.

Contoh Soal
Pengemudi sepeda motor sedang melaksanakan atraksi dalam permainan tong edan di pasar malam. Jika jari-jari tong edan 5 m. Berapa kelajuan minimum (dalam satuan km/jam) yang harus dijalankan pengemudi semoga tidak jatuh sewaktu berputar (μs = 0,7)?

Penyelesaian:
R = 5 m
μs = 0,7
g = 10 m/s2

Kelajuan minimum yang harus dijalankan pengemudi semoga tidak jatuh sewaktu berputar yakni:
v2 = gR/μs
v2 = (10 m/s2)(5 m)/(0,7)
v2 = (35 m2/s2)
v = √(35 m2/s2)
v = 5,9 m/s
(ingat 1 m/s = 3,6 km/jam)
v = (5,9)(3,6 km/jam)
v = 21,24 km/jam
Jadi, kelajuan minimum yang harus dijalankan pengemudi semoga tidak jatuh sewaktu berputar di tong edan ialah 21,24 km/jam.
