Question

A uniform rod of mass m = 60 kg leans against a wall as shown in the figure

below. The wall and floor meet at a right angle and tied from this right

angle to the center of the rod is a string, as shown in the figure below.

The rod makes an angle ? = 23? with floor and there is no friction between

the rod and the wall, but there is friction between the rod and the floor

with ?s = 0.6. If the static friction between the floor and the rod is at its

maximum value, compute the magnitude of the tension in the string that

connects the center of the rod with the point where the wall and floor meet.

(a) 246.26N (b) 346.26N (c) 446.26 N

(d) 546.26N (e) 646.26N (f) Noneoftheabove.

Tension in the string T = mgcos = (d) 546.26N
