PROBLEM 6.124
A 100-lb force directed vertically downward is applied to the
toggle vise at C. Knowing that link BD is 6 in. long and that
a = 8 in., determine the horizontal force exerted on block E.
PROBLEM 6.125
The control rod CE passes through a
horizontal hole in the body of the toggle
system shown. Knowing that link BD is 250
mm long, determine the force
Q
required to
hold the system in equilibrium when
20.
PROBLEM 6.126
Solve Problem 6.125 when (a)
0,
