A simple machine has an IMA of 7. If the effort force of 5N is applied over a distance of 4m, what is the ideal resistance force, and how far does the load travel?a) Fr = 0.71 N and dr = 0.57 m. b) Fr = 0.71 N and dr = 28 m. c) Fr = 35 N and dr = 0.57 m. d) Fr = 35 N and dr = 28 m.

Option C

Explanation:

From the question we are told that:

Effort force

Effort distance

Generally the equation for IMA is mathematically given by

In Terms of Distance

In Terms of Force

Therefore

and

Option C

elctricity and magnet is conversion to it

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
