hey plus com ed ugen/ti/main uni Chapter 12, Problem 028 In the figure, suppose the length L of the uniform bar is 2.6 m and its weight is 250 Also, the block's weight w- 340 N and the angle e 45 The wire can withstand a maximum tension of 410 N. (a) What is the maximum possible distance x before the wire breaks? With the block placed at this maximum are horizontal and (c) vertical components of the force on the bar from the hinge at A?

given
w = 250 N
L = 2.6 m
W = 340 N
Tmax = 410 N
theta = 45 degrees
As the bar is in equilibrium, net force and net torque acting on it must be zero.
a)
Apply net torque about hinge, Tnet = 0
Tmax*L*sin(45) - w*(L/2)*sin(90) - W*x*sin(90) = 0
x = (Tmax*L*sin(45) - w*(L/2))/W
= (410*2.6*sin(45) - 250*2.6/2)/340
= 1.26 m <<<<<<<<-------------------Answer
b) Apply, Fnetx = 0
Fhx - Tmax*sin(45) = 0
Thx = Tmax*sin(45)
= 410*sin(45)
= 290 N <<<<<<<<-------------------Answer
c) Apply, Fnety = 0
Fhy + Tmax*cos(45) - w - W = 0
Fhy = w + W - Tmax*cos(45)
= 250 + 340 - 410*cos(45)
= 300 N <<<<<<<<-------------------Answer
