Mechanics Of Materials Flashcards
1
Q
Shear force at on simply loaded beam
(Two supports at each end)
A
V = (W_o*L)/2
2
Q
Maximum shear force
A
τ = (3V)/(2A)
3
Q
In plane shear stress
A
τ_max,ij = |(σ_i - σ_j)/2|
4
Q
What criteria govern the thin-walled pressure vessels definition?
A
Radius and thickness of tank
5
Q
Reminder
A
READ CAREFULLY
6
Q
For max normal stress in thin-walled vessel
A
Use the σ_t Eq but use (r+t/2)
7
Q
The coefficient of thermal expansion of material is:
A
The strain due to a one-degree change in temperature
8
Q
Stress =
A
Pressure!
So
V/A = F/A
