Question
The pillar is a cylinder that has a diameter of 68 mm , modulus of elasticity of E = 200 GPa . It is is fixed at A and B. The support at A is concrete and therefore rigid.
The support at B can be considered rigid only if the reaction force at B does not exceed 110 kN . The lengths are LAB = 6.4 m and LAC = 3 m .
1)What is the maximum load, P, that can be applied such that the reaction at B does not exceed 110 kN ?
2)What is the reaction force at support A?
