Term
What are the units of shear stress?
Definition
force per area, like psi or MPa
Term
To solve for the maximum shear stress, what is Q for a rectangle with a base of 2 and a height of 6?
Definition
Q = area * distance

max. is at the ENA

y bar = 3"

area = 3" x 2" = 6 in^2

distance = 3/2 = 1.5"

Q = 9 in^3
Term
What are the units of Q?
Definition
length cubed, like in^3 or mm^3
Term
If you have a T cross-section and are asked to find shear stress at the junction between web and flange, what do need to remember?
Definition
You have to do the shear stress calc twice: one with the large thickness and the other with the small thickness.

There is a jump in shear stress plot when the thickness is discontinuous.
