750 N is Fig. 1 shows a simple six bar linkage held in static equilibrium while a force P applied. Determine the reaction forces at each joint and the reaction torque T by considering the free-body diagrams of each member. Each small square on the grid is 50 mm by 50 mm.

I received an answer for my last question and I am still a bit confused. In the solution you said that F only has a horizontal component, how did you arrive at that? The question says that F is down and to the left.

2. Refer to the figure below. In addition to the load at point D, if another load Q (Q=10F) along x direction acts at the center of the right end section of bar OABC, solve for the maximum load F with a safety factor of 2.0 using the maximum shear stress theory. Find the stresses at the origin point O. Assume the yield strength of the steel is 42 kpsi with v=0.3. Hints: The centroid of a semicircle lies at a distance of 4r/(3) measured along the vertical radius (r) or y-direction. 2 in. 1-in D. -in R. 1-in D. 12 in 15 in 1-in D.
