For the screw clamp shown, a force is applied at the end of the handle 3 in from the screw centerline. The 큼 in diameter handle is made of cold-drawn AISI 1006 steel. The screw is in-10 UNC and is 8 in long, overall. The maximum possible length of screw in the clamping region is 6 in. (a) What screw torque will cause the handle to bend permanently? (b) What clamping force will the answer to part (a) cause if...
2. The C clamp shown in the figure below uses an Acme thread screw. The screw has a diameter of 17 mm and a pitch of 5 mm. The frictional coefficients are 0.15 for the threads and 0.20 for the collar. The collar, which in this case is the anvil striker's swivel joint, has a friction diameter of 25 mm. Find the clamping force if 105 N force applied to the handle at a distance of 100 mm from the...

Look at the attached question, thanks. (final answers provided) A screw clamp similar to the one shown in the figure has a handle with diameter 3/16 in made of cold-drawn AISI 1006 steel. The overall length is 4.25 in (not needed) The screw is 3/4 in-10 UNC and is 8 in long. Distance A is 3 in. The length of the handle is 4.1875 in (not needed) The clamp will accommodate parts up to 6 in high. The screw has...

The C-clamp shown in Fig. 2 uses a double threaded square screw with minor diameter 32 mm and pitch of 4 mm. The frictional coefficients are 0.2 for the threads and 0.15 for the collar. The collar has a friction diameter of 50 mm. i. Determine the maximum force P to be applied to the handle at a radius 5 cm from the screw centreline if the clamping force is F-50 N Evaluate whether self-locking occurs. ii. 5 cm
A compressive force of 450 N is to be applied to the two boards in the grip of the C clamp shown in Figure 13. The threaded screw has a mean diameter of 12 mm and advances 2.8 mm per turn. The coefficient of static friction is 0.20. Neglecting any friction at point A Determine the force F which must be applied to the handle at C in order to i. Tighten the clamp to provide the clamping force. ii....
