Co 4.2 ft 40° 6 in 30° Figure P2.79 2.80 The figure shows one-half of a universal coupling known as the Hooke's joint. The coupling is acted on by the three couples shown: (a) the input couple consisting of forces of magnitude P, (b) the output couple Co, and (c) the cou formed by bearing reactions of magnitude R. If the resultant of these couples is zero, compute R and Co for P 750 lb. Figure P2.80

The Question The above figure (not drawn to scale) shows a rectangular beam with a depth of d = 32mm and breadth of b = 50mm subjected to a combined loading of F = 50kN direct load and M-150Nm bending load. The bending moment is acting about the depth of the beam (causing it to bend about its depth, d). Calculate the second moment of area, I, in m in the form ax 10"" where the number a is correct...
