Explain why the output work for any machine cant be greater than the input work

1 answer:

7 0

Answer:

When you input force to do work, the output work cannot be greater than what is

put in, because work is energy, and energy is 'conserved'. That means it can't be

created out of nothing.

Answer:

Explanation:

In friction, the coefficient of friction formula is expressed as;

$\mu = \frac{F_f}{R}$

Ff is the frictional force = Wsinθ

R is the reaction = Wcosθ

Substitute inti the equation;

$\mu = \frac{Wsin \theta}{W cos\theta} \\\mu = \frac{sin \theta}{cos\theta} \\\mu = tan \theta$

Given

θ = 24°

$\mu = tan 24^0\\\mu = 0.445\\$

Hence the coefficient of kinetic friction between the box and the ramp is 0.445

Less because now there is less force on the scale and you are unbalanced. Therefore the scale will have a lower number then before.
