Question
The figure provided demonstrates two masses at rest. If the mass of each block is 27.6 kg, what does the scale read? Assume the string and pulley to be massless. The scale reads 0 kg. The scale reads 13.8 kg. The scale reads 27.6 kg. The scale reads 55.2 kg.
Solution
The question seems to be incomplete as there is no figure provided. However, if we assume that the two masses are hanging on either side of a pulley in equilibrium, then the scale under one of the masses would read the weight of that mass.
The weight of an object is the force of gravity acting on it. It can be calculated using the formula:
Weight = mass x gravity
Where the gravity is approximately 9.8 m/s^2 on Earth.
So, for a mass of 27.6 kg, the weight would be:
Weight = 27.6 kg x 9.8 m/s^2 = 270.48 N
However, scales in everyday use typically measure weight in kilograms, not Newtons. They do this by dividing the weight of the object by the acceleration due to gravity. So, if we put this weight back into kilograms, we get:
Weight = 270.48 N / 9.8 m/s^2 = 27.6 kg
So, the scale would read 27.6 kg.
