By an adequate application of the Principle of Energy Conservation, the escalator need energy to elevate from to the bottom to the top. Hence:
An expression for power needed is found by deriving the equation with respect to time:
The minimum power is found by substituting known inputs:
Answer:
Tire inflation can be caused by temperature and speed :)
Answer:
E=1.969 × 10¹¹ Pa
Explanation:
The formula to apply is;
E=F*L/A*ΔL
where
E=Young modulus of elasticity
F=Force in newtons
L=Original length in meters,m
A=area in square meters m²
ΔL= Change in length in meters,m
Given
F= 8000 lb = 8000*4.448 =35584 N
L= 5 in = 0.127 m
A= 0.7 in² =0.0004516 m²
ΔL = 0.002 in = 5.08e-5 m
Applying the formula
E=(35584 * 0.127)/(0.0004516*5.08e-5 )
E=1.969 × 10¹¹ Pa
