Answer:
To distinguish results based on the only two variables of
awareness.
Explanation:
Answer:
A. Shear stresses are maximum at the neutral axis and normal stresses are maximum furthest from the neutral axis.
Explanation:
Normal stress :
Normal stress is defined as the stress or the restoring force that occurs on the plane when an external axial load is applied on it. For a beam the normal stress is maximum at the point furthest from the neutral axis and is zero at the neutral axis of the beam.
Shear stress :
Shear stress is a stress which occurs when the force acts on the surface of the member in a parallel direction. It changes the shape of the member. For a beam, the shear stress is maximum at the neutral axis.
Answer:
The can mass is 0,00359 kg or 3,59 g
Explanation:
1. Relevant Data:
Steel thickness= 0.13 mm or 0.013 mm
h=11 cm
d=6 cm
ρ=800 kg/m^3
2. Calculate mass from densisty equation:
, then 
We need to estimate the volume of the can to calculate the mass.
3. Estimate volume using differentials:
Cylinder volume equation is:

Considering that the can is an object with a hole inside, then we need to estimate the real volume of the sheet of steel.
Using differentials we have:

Then, we could say that 
Replacing the values of d, h and dD, we obtain:


4. Calculate the mass
Convert volume unit into 

Calculate mass



Force decreases as distance increases
