Compute for the force that the muscle should exert in order to (1) maintain it in the position and(2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm,distance of the weight is 80 cm, and the COM is 45 cm from the joint. ANSWER THE QUESTION: 1.) Assuming that the leg moves at 0. 9 seconds, compute for the angular velocity. GIVEN: Leg length = 84 cm = 0.84 m Distance of the muscle from the joint = 54 cm = 0.54 m Distance of the weight = 80 cm = 0.80 m Distance of the COM from the joint = 45 cm = 0.45 m Mass = 10 lb = 4.535 kg Linear displacement x = 38.971 cm Or x = 0.389 marrow_forward1.

The center of mass of this ladder is 1/3 of the way up from the bottom (it gets narrower towards the top). A person of mass M then decides to climb the ladder until he comes to the halfway point. Wall has no friction but the ground has on the ladder.. a) Draw this situation and label forces so you may set up the statics equations. b) Find the force on the ladder due to the ground (both x and y components) and the force on the ladder due to the wall.arrow_forward
