Question 1 Report

An effort of 40N is applied on a machine to lift a mass of 60kg. Determine the mechanical advantage of the machine [ g = 10ms2 2  ]
Answer Details

To determine the Mechanical Advantage (MA) of a machine, we use the formula:


MA = Load / Effort


Here, the Load is the weight of the mass being lifted, and the Effort is the force applied on the machine.


First, we need to calculate the Load. The Load is obtained by multiplying the mass of the object by the acceleration due to gravity (g = 10 m/s2).


So, the Load (weight of the mass) is:


Load = Mass × Gravity = 60 kg × 10 m/s2 = 600 N


The Effort given is 40 N.


Now, we can calculate the Mechanical Advantage:


MA = Load / Effort = 600 N / 40 N = 15


Therefore, the Mechanical Advantage of the machine is 15.
