The mechanism shown in is used to raise a crate of supplies from a ship's hold. The crate has total mass 54.0 kg. A rope is wrapped around a wooden cylinder that turns on a metal axle. The cylinder has radius 0.04 m and moment of inertia I= 2.4 kg•m² about the axle. The crate is suspended from the free end of the rope. One end of the axle pivots on frictionless bearings; a crank handle is attached to the other end. When the crank is turned, the end of the handle rotates about the axle in a vertical circle of radius 0.12 m, the cylinder turns, and the crate is raised. What magnitude of the force FS applied tangentially to the rotating crank is required to raise the crate with an acceleration of 1.40 m/s?

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

The mechanism shown in is used to raise a crate of supplies from a ship's hold. The crate has
total mass 54.0 kg. A rope is wrapped around a wooden cylinder that turns on a metal axle. The
cylinder has radius 0.04 m and moment of inertia I = 2.4 kg-m² about the axle. The crate is
suspended from the free end of the rope. One end of the axle pivots on frictionless bearings; a
crank handle is attached to the other end. When the crank is turned, the end of the handle rotates
about the axle in a vertical circle of radius 0.12 m, the cylinder turns, and the crate is raised.
What magnitude of the force F S applied tangentially to the
rotating crank is required to raise the crate with an
acceleration of 1.40 m/s?? (You can ignore the mass of the
rope as well as the moments of inertia of the axle and the
crank.)
I0.12 m
