For the shown frame: 1.Determine the reactions at Pin A and at B. 2.What is the force developing in Cable BE 3.Find the Internal forces at point C 300N 1 m D 1 m- -1 m- 2 m- 500N.m

Select the distance a between 2 m and 5 m and the force P between 15 kN and 35 kN in the cage system shown in the figure and find the rod forces. Also note that the forces on the rods did not compress my tension. (AE, AB, BE, DE, CD, BC, BD =?)

It is desired to remove the spike from the timber by applying force along its horizontal axis. An obstruction A prevents direct access, so that two forces, one 460 lb and the other P, are applied by cables as shown. Compute the magnitude of P necessary to ensure a resultant T directed along the spike. Also find T. 10" 4" 7" 460 lb Answers: i Ib %3D T = i Ib
