How to find acceleration on an inclined plane without friction Two coplanar forces act on an object as shown. Which diagram shows the resultant F of these two forces? When drawing a free-body diagram, how should vectors be drawn? How to find the coefficient of friction ...
Explain the concept behind the Pulley Problems and River Boat Problems Why is it important to precisely know acceleration due to gravity? How does a DC motor work? In an Atwood machine, why do the tensions that handle both bodies are the same?
A pulley is a wheel on an axle designed to assist in the movement of heavy loads. A one-wheel pulley allows you to change the direction of the force you have to apply to lift the load by pulling down to lift a load upwards. Similarly, a two-wheel pulley splits the weight equally ...
The rim of the pulley moves together with the string, it has the same linear acceleration and angular acceleration α=a/r. The equation between torque and angular acceleration is τ=Iα. One string turns the pulley in one direction, the other rotates it to the opposite direction. The net ...
The latter car, on the other hand, would fly at 80 mph down the highway, but it would have almost no acceleration when starting out and wouldn't be able to climb hills. So the transmission uses a range of gears -- from low to high -- to make more effective use of the engine's...
The first "real" race we had was a huge difference. The mower did much better. That said, there are still some issues. The biggest is that I chose not to install a high performance cam. This would greatly help with low end torque and faster acceleration out of the corners. This is ...
Acceleration due to gravity (g) = 9.81m/s2, Tension in the rope = T +↑ ΣFy -10kg * 9.81m/s2 + T = -10a + 1000cos40N Where a is yet to be derived This equation is not correct. The vertical components of the tension forces on the pulley must be balanced by...
About every modeler I have ever known has his or her own ways of accomplishing tasks and you will find yourself asking, “Why did the original builder do it this way?” Most often there was a reason, but sometimes it was just a mistake, an attempt to implement a new idea that didn’...
Burning smell in Toyota Yaris could be harmless or something very serious and a potential fire hazard. Therefore it is recommended to urgently find and...
Testing at Nurburgring and at other high-speed tracks helps automakers gather information about the test car's acceleration, braking and handling capabilities. It has also become something of a marketing tool, as the top manufacturers seek to topple the incumbent record holder each year. These brag...
