Length of cylinder is, L = 0.27 m
Outer radius of cylinder is, r_out = 1.12×10^{-2} m
Inner radius of cylinder is, r_in = 3.9×10^{-3} m
Mass of person, m = 60 kg
Young's modulus , Y = 9.4×10^9 N/m2
(a)
Compressional strain of humerous is,
(b) Let assume that humerous is compressed by ΔL
Since, strain = ΔL/L0
Thus,
Answer:
Explanation:
Work is the product of force and distance.
We know the force to lift the rock was 50 Newtons. The work was 150 Joules.
- 1 Joule is equal to 1 Newton meters.
- We can convert the units to make the problem simpler later. The work is also 150 Newton meters.
Substitute the values into the formula.
We want to solve for distance, so we must isolate the variable. Divide both sides of the equation by 50 Newtons.
The Newtons will cancel out.
The rock was lifted <u>3 meters.</u>
