Propped Cantilever Beam AB Has Moment M1M_{\mathrm{1}} Applied at Joint B M2M_{2}

question 86

Short Answer

Propped cantilever beam AB has moment M1M_{\mathrm{1}} applied at joint B. Framework ABC has moment M2M_{2} applied at C. Both structures have con-
Stant flexural rigidity EI. If the ratio of the applied moments M1/M2=3/2M_{1} / M_{2}=3 / 2 the ratio of the joint rotations at B, θB1/θB2\theta_{B 1} / \theta_{B 2} , is approximately: (A) 1
(B) 3/2 3 / 2
(C) 2
(D) 5/2 5 / 2
