Question

2) Find the force P that must be applied to the number 4 piston in order for the piston number 4 to move at a constant speed in the position shown in the figure of the mechanism whose mass properties are given below. m2 = 3 kg (mass of limb number 2) m3 = 5 kg (mass of limb number 3) $I_{G2}$ = 0.004kg-m2 (Mass moment of inertia around the center of mass G2 of link 2) $I_{G3}$=0.009 kg-m2 (Mass moment of inertia around the center of mass G3 of link 3)

number 4 piston in order for the piston number 4
to move at a constant speed in the position shown
in the figure of the mechanism whose mass
properties are given below.
m2 = 3 kg (mass of limb number 2)
m3 = 5 kg (mass of limb number 3)
$I_{G2}$ = 0.004kg-m2 (Mass moment of inertia around
the center of mass G2 of link 2)
$I_{G3}$=0.009 kg-m2 (Mass moment of inertia around
the center of mass G3 of link 3)

Step 1

We have the force P applied to piston number 4, the weight of limb number 2 (m2g), the weight of limb number 3 (m3g), and the friction force between limb number 3 and the ground (Ffriction). Since the piston number 4 is moving at a constant speed, we know that Show more…
