The steel plate is 0.4m thick and has a density of 7050 kg/m3. Determine the location of its center of mass. And compute the reactions at the pin and roller support.

The bobcat loader (Figure Q3) has a mass of 1200-kg, shows the center of mass is at G1. If there is a 200-kg pebble in the bucket, with center of mass at G2 determine the reactions of each pair of wheels A and B on the ground and the force in the hydraulic cylinder CD and at the pin E. There is a similar linkage on each side of the loader. L0.5 m E 0.1 m_ D 0.2 m G2 0.18 m G1 0.6 m 0.5 m В 0.45 m 1.2 m 0.15 m 0.2 m 0.05 m Figure Q3

calculate the centroid known that  A = 65mm B= 15mm C= 3mm D= 4mm E=30mm
