A 8 000-N shark is supported by a rope attached to a 4.80-m rod that can pivot at the base.
(a) Calculate the tension in the cable between the rod and the wall, assuming the cable is holding the system in the position shown in the figure. (Give you answer to three significant digits.)
N
(b) Find the horizontal force exerted on the base of the rod.
magnitude N
direction
(c) Find the vertical force exerted on the base of the rod. Ignore the weight of the rod.
