Spring Design Problem: You have a big clothespin like tool
holding on to a cable, where the center of it is loaded with a mass
m (5 kg) as shown in the diagram.
Design a torsion spring (finding k, leg length, etc...) and determine the required torque to be applied to each of the both arms of the tool to prevent the tool from slipping from the cable and falling.
Remembering that the holding force (Fh) will be related to the normal force generated by the clamping force and the friction coefficient of the surface of each arm (assume friction coefficient μ is 1.05). And that the holding force must be equal to or larger than the weight of the load (or m*g).
Show all equations and explanations needed to design the torsion spring with its center in the pivot point for both of the tool’s arms.
