PROBLEM 8.46
Two slender rods of negligible weight are pin-connected at C and
attached to blocks A and B, each of weight W. Knowing that
80
and that the coefficient of static friction between the
blocks and the horizontal surface is 0.30, determine the largest
value of P for which equilibrium is maintained.

PROBLEM 8.47
Two slender rods of negligible weight are pin-connected at C and
attached to blocks A and B, each of weight W. Knowing that
P 1.260W and that the coefficient of static friction between the
blocks and the horizontal surface is 0.30, determine the range of
values of θ, between 0 and 180°, for which equilibrium is
maintained.

PROBLEM 8.48
The machine part ABC is supported by a frictionless hinge at
B and a 10 wedge at C. Knowing that the coefficient of
static friction is 0.20 at both surfaces of the wedge,
determine (a) the force P required to move the wedge to the
left, (b) the components of the corresponding reaction at B.

PROBLEM 8.49
Solve Prob. 8.48 assuming that the wedge is moved to the
right.

PROBLEM 8.50
Two 8 wedges of negligible weight are used to move and position the
800-kg block. Knowing that the coefficient of static friction is 0.30 at all
surfaces of contact, determine the smallest force P that should be applied
as shown to one of the wedges.

800-kg block. Knowing that the coefficient of static friction is 0.30 at all
surfaces of contact, determine the smallest force P that should be applied
as shown to one of the wedges.
