Answer 2

Answer:

The maximum shear stress is 3.00N/mm^2.

Shear Stress:

• Shear stress is a force applied to a body that causes the body to deform.
• It acts coplanar to the cross-section of the given body.
• The shear stress is calculated as τ = F/A and has units same as pressure.

Explanation:

Given:

Average shear stress = 2 N/mm^2

To find:

Maximum shear stress

Formula:

Maximum shear stress = 1.5 × average shear stress

Solution:

We know that the maximum shear stress for a beam of rectangular sections is 1.5 times the average shear stress.

Substituting the given value of average shear stress, we get

Maximum shear stress = 1.5 × 2

Maximum shear stress = 3.0 N/mm^2

Therefore, the maximum shear stress in the beam section is 3.00 N/mm^2.
