The C clamp shown in figure- 4 for uses a Acme thread. The frictional coefficients are 0.15 for the threads and for the collar. The collar, which in this case is the anvil striker's swivel joint, has a friction diameter of . Calculations are to be based on a maximum force of applied to the handle at a radius of from the screw centerline. Find the clamping force. Figure-5
Expert Answer
The clamping force exerted by the C clamp, we need to consider the torques involved and use the principle of equilibriumMaximum force applied to the handle= Radius from the screw centerline to the handle Thread diameter Frictional coefficients ( both the threads and the collar)Friction diameter of the collar Calculate the torque applied to the screw:Torque = Force × Radius Torque Torque
