Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. A pulley assembly is designed to measure the weight of block F using a counterweight. Springs G and H (k = 960 N/m) are compressed by 0.2 meters. Knowing that the system is in equilibrium, determine the mass of block F. Also, determine the tension carried by cable AI and the forces from bar A and bar C. Notes!There's a single cable from point J to point B. This cable is not attached to the cable from C to F. This cable is also not attached to the horizontal bar at C. There's also a single cable running from A to block M. This cable is not attached to the horizontal bar at A. L is also a block with mass 41 kg.

Three bars, two made of aluminum and one made of steel, support a rigid block. An object of weight W is dropped vertically from a distance h above the rigid block. Both steel and aluminum bars have cross-sectional area of 50 mm2 and length of 0.5 m. The elastic moduli for the aluminum and steel are 76 GPa and 184 GPa, respectively. a) If W=1000N and h=0.1m, determine whether the three bars are still safe to perform. b) If h=0.2m, determine the maximum weight that can be dropped without causing failure to the bars
