The section of a crane hook is rectangular in shape whose width is 30 mm and depth is 60 mm. The centre of curvature of the section is at a distance of 125 mm from the inside section and the load line is 100 mm from the same point. Find the capacity of the hook, if the allowable stress in tension is 75 MPa. Also determine the location of the neutral axis and the stress at inner and outer fiber.

Find p1 and p2

Attempt only if you are sure.

Calcuate Shear and Bending From Point A to Point B and Point A to Point C. Draw a FBD from point A to point B and another for point A to C indicating what stresses are been calculate. Use the stress tensor and stress cube to Indicate what forces are acting at point A. Force apply at point B is 70lb Distacen from Point A to B is 12 in or 1 feet long Distacen from Point A to C is 3 in Handle diameter 0.625 in

Find the interal normal stress in all relevant segments of the bar in the picture.

A tie rod of ¼ inch diameter is used to hold a plaster wall in place. The tensile stress in the rod caused by load P is 20 ksi.  Find the diameter “d” (to the nearest 1/6 inch) of the washer that keeps the bearing stress between the plaster and the washer from exceeding 300 psi.

For the bar in the way the loading status is seen determine the strain energy on the rod so that the shear stress on the rod is maximum 120 MPa.( Part of BC is hollow)

How do I calculate for sigma seam?   Thank you

This problem illustrates that the factor of safety for a machine element depends on the particular point selected for analysis. Here you are to compute factors of safety, based upon the distortion-energy theory, for stress elements at A and B of the member shown in the figure. This bar is made of AISI 1006 cold-drawn steel and is loaded by the forces F= 0.55 kN, P = 4 kN, and T = 25 N·m. Given: Sy= 280 MPa. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 15-mm D. -100 mm- P

compute the maximum stress in the member, considering stress concentrations.
