- The problem is stated below. However, change the position of torque to point C from point D. What is the effect of variation of torque placement in shaft CB?arrow_forwardThe answer is 1290N, but I am not entirely sure how they got there. However, I noticed that when I calculated the torques for the person and that of the ladder, my answer would be correct if I multiplied by sin(60) or cos (30) instead. Using the sum of these values, I would divide it by the length of the ladder and sin(30), which would give the correct answer, but I'm a bit confused as to why I need to take sin(60) or cos(30) to calculate the torques for the weight of the ladder and the human, but then use sin(30) when calculating the torque for the perpendicular force. I would appreciate a work through of the problem and some explanation for my difficulties above, thank you.arrow_forwardA 220 mm diameter of 14.5 degrees involute gear is used to transmit 50 kW at 580 rpm Find the total force transmitted on the gear.arrow_forward
