PROBLEM 4.29
Rod ABC is bent in the shape of an arc of circle of radius R. Knowing the
30, determine the reaction (a) at B, (b) at C.
PROBLEM 4.30
Rod ABC is bent in the shape of an arc of circle of radius R. Knowing that
60, determine the reaction (a) at B, (b) at C.
PROBLEM 4.31
Neglecting friction, determine the tension in cable ABD and the
reaction at C when
60.
PROBLEM 4.32
Neglecting friction, determine the tension in cable ABD and the
reaction at C when
45.
PROBLEM 4.33
A force
P
of magnitude 90 lb is applied to member ACDE, which is
supported by a frictionless pin at D and by the cable ABE. Since the
cable passes over a small pulley at B, the tension may be assumed to
be the same in portions AB and BE of the cable. For the case when
a 3 in., determine (a) the tension in the cable, (b) the reaction at D.
PROBLEM 4.34
Solve Problem 4.33 for a 6 in.
PROBLEM 4.33
A force
P
of magnitude 90 lb is applied to member
ACDE, which is supported by a frictionless pin at D and by the cable
ABE. Since the cable passes over a small pulley at B, the tension may
be assumed to be the same in portions AB and BE of the cable. For
the case when a 3 in., determine (a) the tension in the cable, (b) the
reaction at D.
