A solid copper cylinder of length `l=65cm` is placed on a horizontal surface and subjected to a vertical compressive force `F=1000N` directed downward and distributed uniformly over the end face. What will be the resulting change of the volume of the cylinder in cubic millimeters?

A metal cylinder of length L is subjected to a uniform compressive to a uniform compressive force F as shown in the figure. The material of the cylinder has Young's modulus Y and poisson's ratio sigma The change in volume of the cylinder is

A uniform thin rod has mass m and length l. One end of the rod lies over rough horizontal surface and the other end is connected to a light vertical string as shown in the figure. When string is cut, there is no slipping between rod and surface.Calculate the friction force (in N) on the rod immediately after the string is cut .(Given mg=(16)/(sqrt(3))N )

A uniform rod of mass m and length l is placed over a smooth horizontal surface along the y -axis and is at rest as shown in Fig. An impulsive force F is applied for a small time /_\t along x -direction at point A . The x -coordinate of end A of the rod when the rod becomes parallel to x -axis for the first time is [initially, the coordinate of centre of mass of the rod is (0, 0) ]
