Shaft Design Flashcards
1
Q
Shear stress on keys
A
τd = F / As
2
Q
Shear stress on keys eqs simplified down further
A
F / As = (2T / D) / (W L)
3
Q
Rearrange Shear stress eqs for L
A
L = 2 T / (τd D W)
4
Q
Shear stress eqs to account for safety factor
what is N
A
τd = 0.5 σy / N
where N is the safety factor
5
Q
Bending stress on a key
A
σd = F / Ab
6
Q
Bending stress on keys eqs simplified down further
A
F / Ab = (2T / D) / (LH / 2)
7
Q
Rearrange Bending stress eqs for L
A
L = 4T / (σd D H)
8
Q
Finding σd using σy eqs
what is N
A
σd = σy / N
where N is the factor of safety
