An 80.0 kg constructor worker sits down 2.00 m from the end of a 1460 kg horizontal steel beam to eat his lunch, as shown in the figure. The 8.00 m long beam is supported by a cable attached at P to the wall, and is hinged at H in the wall. ?= 40 degrees. (a) Find the force of tension, FT, in the cable, and (b) find the force by the hinge, FH, supporting the beam.

A rectangular block is 6 in. long in the x – direction, 4 in. long in the y – direction, and 7 in. long in the z - direction. The block is subjected to triaxial loading consisting of the three normal forces as follows: 45 kips in tension in the x – direction, 72 kips in tension in the y – direction, and 56 kips in compression in z - direction. Use v = 0.30 and E = 29 x 10° psi. What is the deformation in the X and Z direction due to original loadings? Determine the uniformly distributed load that must be added in the x – direction that would produce twice the deformation in the y – direction as the original loadings.
