I think that when work is done and a force istransferred an object must move in the direction of the force.
The increase in potential energy is
Explanation:
The gravitational potential energy gained by an object lifted above the ground is given by:
where
m is the mass of the object
g is the acceleration of gravity
is the change in height of the object
For the beam in this problem, we have
m = 330 kg
Substituting, we find its gain in potential energy:
