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.
Calculate the weight of the beam. Use g = 9.8 m/s^2.

The weight of an object can be calculated using the formula:

Weight = mass x acceleration due to gravity

Given that the mass of the concrete beam is 120 MT (metric tonnes), we need to convert it to kilograms (kg). Since 1 MT equals 1000 kg, the mass of the beam is:

Mass = 120 MT x 1000 kg/MT = 120,000 kg

The acceleration due to gravity is given as g = 9.8 m/s^2.

Therefore, the weight of the beam is:

Weight = Mass x g = 120,000 kg x 9.8 m/s^2 = 1,176,000 N
