QUESTION 5 A force of P=312 N is applied to the 48-kg cart. Determine the reaction at Othe wheel at A. The mass center of the cart is at G. take c = 0.5m and d=0.17m. (See figure (3) c(m) H+ 0.08 m 0.3 m * 0.2 m -
Calculate the forces that the supports A and B exert on the
diving board shown in (Figure 1) when a 58-kg person stands at its
tip.
Part A
Calculate the force that the support A exerts on the diving
board. Ignore the weight of the board.
Express your answer to two significant figures and include the
appropriate units. Enter positive value if the force is upward and
negative value if the force is downward.

QUESTION 5a A system consists of a 0.6 kg rod AOB and 0.6 kg disc CD is attached to each other with cable BD. Figure Q5a shows that at position 1, the rod is vertical when it started to move due to moment M = 2.4 Nm that wind up the cable to the disc one cycle until the rod reaches horizontal position at 2. Determine the rotational velocity of the rod, waob at position 2. The spring attached to...
Question 1 1.5 pts A 56 kg rock climber has positioned himself as shown in the figure (with his hands on one side of a gap and his feet on the other side). Both friction and normal forces act on his hands and feet. The width of the gap, w, is 0.30 m and the climber's center of mass is a horizontal distance d = 0.37 m from the gap. The coefficient of static friction Mi = 0.45 between his...
