To calculate the potential energy of the beam when it is halfway the target height, we need to determine the gravitational potential energy formula and substitute the values into it.
The gravitational potential energy formula is given by:
Potential Energy = mass x gravity x height
Given:
Mass of the beam (m) = 120 MT = 120,000 kg (since 1 MT = 1000 kg)
Target height (h) = 7.5 meters
To find the potential energy when the beam is halfway the target height, we need to divide the target height by 2:
Halfway height = 7.5 meters / 2 = 3.75 meters
Now, we can substitute the values into the formula:
Potential Energy = mass x gravity x height
Potential Energy = 120,000 kg x 9.8 m/s^2 x 3.75 meters
Calculating the potential energy:
Potential Energy = 4,410,000 Joules
Therefore, the potential energy of the beam when it is halfway the target height is 4,410,000 Joules.
A 120-MT concrete beam is lifted from the floor by two tandem heavy lift cranes up to a target height of 7.5 meters.
