Refer to Fig. 9-36. The angle of static friction between the block with mass M and the plane is d. For the angles shown in the figure, what is the expression for the force P to move the block up the plane? P = [9.8M sin (0 + ¢)]/[cos (B - 6)]

The simple truss is loaded by a system of forces as shown in the figure. The truss is supported by a pin at A and a roller at E. If P1 = 40 [KN] and P2 = 20 [KN], then the force developed in the member (EF) is.

The figure on the left, below, shows a non-uniform bent rod with a mass of 5 kg. Your job is to determine the location of the center of gravity of this rod. You design an experiment: you connect a pin and cable to the rod such that it safely stays in static equilibrium under a force P that you apply. Then, you apply forces between 0-100 N, and measure the tension force on the cable using a cable tension meter. The results of your experiment are shown in the figure, on the right. Using this experiment, calculate (approximately) the horizontal distance (x in the figure) between point A and the center of gravity G of the bent rod.

Hi, I think you forgot to divide the answer by 2 as indicated in your initial formula. Moreover, I tried solving the problem using the formula I attached as image here and I got a positive value of the answer you came up with. What answer would be the right one? Also, please explain the cause and effects of having that certain value of theoretical pressure drop in the problem. Thank you so much!

Figure The figure shows a schematic of an engine. F, is the force exerted by the combustion gases on the piston (shown by the rectangle at B). FÅ= 50 kN. The angle of the crank OA is 0 = 30° while the angle of the connecting rod AB is p = 15°. Neglect the weight of all members. Also neglect friction between the piston and the cylinder.
