Review of Statics - Example
Determine the reactions at A and C. The system is pin-
supported at A and roller-supported at C. Neglect the
weight of the system.
Review of Statics - Example
EFx: Ax + 500 = 0
Ax = -500 N
Ax = 500 N (to the left)
EFy: Ay + Cy=0
EMA: 500(2) 2 Cy = 0
Cy 500N (up)
EFy: Ay+ Cy=0
EFy: Ay+ 500 = 0
Ay=-500 N
Ay = 500 N (downwards)

SHEARING STRESS: If the force is parallel to the cross
sectional area
Shear Stress - Example
The bearing pad consists of a
150 mm by 150 mm block of
aluminum that supports a
compressive load of 6 kN.
Determine the shear stress
acting on the plane through
section a-a.
