Question

A concrete block of size 0.6mx0.75mx0.5m is cast with a hole of diameter 0.2 m and depth 0.3m as shown in figure. The hole is completely filled with steel balls weighing 2500 N. Locate the centre of gravity of the body. Take the weight of the concrete =25000N/. A body resting on a horizontal plane required a pull of 80N inclined at 300 to the horizontal just to move it. It was also found that a push of 100N inclined at 300 to the horizontal just moved the body. Find the weight of the body and the coefficient of friction.​
