Question

If the IMA of a machine is 4 and the effort force is 6.0 newtons, then the force exerted on the resistance by the machine is _____.
A- 1.5 N
B- 2.0 N
C- 10 N
D-24 N

Answer 1

Answer:The correct answer is option D.

Explanation;

Ideal mechanical advantage is defined as ratio of force exerted by the machine to the force applied on the machine.

$I.M.A=\frac{Force_{out}}{Force_{in}}$

$I.M.A=4=\frac{Force_{out}}{6.0 N}$

Output force = 24 Newtons

Hence,the correct answer is option D.

Answer 2

If the IMA of a machine is 4 and the effort force is 6.0 newtons, then the force exerted on the resistance by the machine is D-24 N
