3.58 Determine the tension developed in each of
the cables, AB, AC and AD required for
equilibrium of the 75-kg cylinder.

3.67 Three cables are used to support a 700-lb
ring. Determine the tension in each of the cables
AB, AC and AD for equilibrium.
F4-5 Determine the direction of the moment of
the force about point O. Neglect the thickness
of the member.
4.20 The tongs are used to grip the ends of the
drilling pipe P. If a torque (moment) of
MP = 730 lb-ft is needed at P to turn the pipe,
determine the cable force F that must be applied to
the tongs. Set
o
= 30 .

4.30 If FB = 35 lb and FC = 35 lb,
determine the resultant moment about the
bolt located at A.
4.36 The wheelbarrow and its contents have a
center of mass at G. If F = 90 N and the
resultant moment produced by force F and the
weight about the axle at A is zero, determine the
mass of the wheelbarrow and its contents.
