2. A uniform, solid disk of radius R is attached with a large pin to the horizontal table at point C (the center of the disk) so that it can freely rotate around the orthogonal axis that passes through the point C. Three forces, F₁, F2 and F3, which act in a plane of table, are applied to the disk as shown in the figure. (Force F2 makes angle theta relative to the radius of the disk.) Write the equation that need to be satisfied in order to prevent disk's rotation around the point C. F1 R 8 F2 F3
1. A uniform rod of weight W and length L, at the zoo is held in a horizontal position by two ropes at its ends (Fig. below). The left rope makes an angle of 150° with the rod and the right rope makes an angle theta with the horizontal. A monkey (Alouatta seniculus) hangs motionless at distance d, from the right end of the rod. a. Draw a free-body diagram of the rod. b. Write condition for rotational equilibrium for the rod with respect to the center of gravity of the rod. 150 2.50 m 0.50 m
