Answer:
The force needed to lift the load is 133.33 N.
Step-by-step explanation:
Given;
load to be lifted, L = 2000 N
mechanical advantage of the machine, M.A = 15
Mechanical advantage is calculated as;
M.A = L / E
where;
E is the effort or force needed to lift the load.
Substitute the given values and solve for E
E = L / M.A
E = (2000) / (15)
E = 133.33 N
Therefore, the force needed to lift the load is 133.33 N.
