uniform. What is the center of gravity? Clearly a net gravitational force of F ( m 1 m 2 m 3 m 4)g would give the same total gravitational force. M to represent the sum of the 4 masses. The left tire exerts no torque about this point since the torque arm is zero. There is no way these two torques can cancel. Hey, let's just move this really heavy object over here. Where could I put this one gravitational force so that it gives the same torque about some point (point o in this case)?
Center of gravity Essay Example for Free A Crane, A Tank, and the Center of Gravity wired
Modeling the motion of a falling slinky. Oh, you don't like that? In physics, an object is in equilibrium when it has zero acceleration when the net force acting on it is zero. Here are some other examples of tipping or not tipping over with the center of gravity (for your reading pleasure). Here is an extreme example. No one has time to calculate that many forces (it's too hard even for a computer). For, this case, I can use the simplified calculation of torque as: Torque should actually be described as a vector, but this definition will work here. When dealing with torques, it's not just the magnitude of the force that matters but also the location.
