PROBLEM 10.18
The pin at
C
is attached to member
BCD
and can slide along a slot cut in
the fixed plate shown. Neglecting the effect of friction, derive an
expression for the magnitude of the couple
M
required to maintain
equilibrium when the force
P
which acts at
D
is directed (
a
) as shown, (
b
)
vertically downward, (
c
) horizontally to the right.
