... take the gradient of the line. But if the acceleration is non-uniform it is, by definition, changing. So we can only work out the acceleration at specific points, or instants. We call this taking the instantaneous acceleration. Graph A shows the V-T graph of an object with non-uniform acceleration. ...

... The four bodies shown in the figure have equal masses m. Body A is a solid cylinder of radius R. Body B is a hollow thin cylinder of radius R. Body C is a solid square with length of side 2R. Body D is the same size as C, but hollow (i.e.) made up of four thin sticks). The bodies have axes of rotati ...

... Analysis of a rigid eccentric cam involves the determination of the contact force, the spring force and the cam shaft torque for one revolution of the cam. In simplified analysis, all the components of the cam system are assumed to be rigid and the results are applicable to low speed systems. Howeve ...

... If there is some friction, it is the net force of your push minus the frictional force that is multiplied by distance to give the gain in kinetic energy. If the box moves at a constant speed, you are pushing just hard enough to overcome friction. The net force and net work are zero, and, according t ...

Rotational Dynamics
... To observe how an extended object rotates when a torque is exerted on it, use a pencil with coins taped at the ends. Hold the pencil between your thumb and forefinger, and wiggle it back and forth. The forces that your thumb and forefinger exert, create torques that change the angular velocity of th ...
