Finding the average shear stress

AI Thread Summary
The discussion focuses on calculating shear stress along a cylindrical area of a plate and the average shear stress in a bolt head. Key parameters include the plate thickness of 30 mm, bolt head thickness of 8 mm, bolt head diameter of 18 mm, and shank diameter of 7 mm, with an axial load of 8 kN. Participants discuss using the ultimate shear stress equation and the area of a circle to find the necessary values. One user confirms they resolved the problem after clarifying their thoughts. The conversation highlights the importance of understanding the relationship between force, area, and shear stress in mechanical applications.

Homework Statement


Find the shear stress alone the cylindrical area of the plate, and the average shear stress in the bolt head along the cylindrical area.

the plate is 30 mm thick

bolt head is 8 mm thick

bolt head diameter is 18mm

bolt shank diameter is 7 mm

shank has 8 kn along it

Homework Equations


Ultimate Shear Stress Equation: [/B]T(u) = F/A

Area of a Circle: A = (pi*d^2)/4

The Attempt at a Solution



For the plate, would i plug 8 kN into "F" variable, and multiply the area of the bolt head by the thickness of the plate??

What is the annular area of the shank? What is the axial force acting on this area? What is the normal stress on the shank?

thanks for the reply chet however i have already solved this problem. The only thing needed was a clear head. Once again thanks for the response it is appreciated.
