Question
An assembly plant uses a hoist to raise and maneuver large objects. The hoist shown in
Figure is a winch attached to a beam that can move along a track. Determine the natural
frequency of the system when the hoist is used to raise a 800-kg machine part at a cable
length of 9 m.
Beam
The beam is modeled as a pinned-pinned beam. If the hoist is at
its midspan, its stiffness is
48 EI
1.3
Cable

Beam: L = 3.1 m
E = 200 x 10° N/m²
1=3.5 x 104 m²
Cable: E= 200 × 10⁹ N/m²
r = 10 cm
L = 9 m
