ENGR 2143- Strength of Materials Homework 9 Name 1 pts) Points 35 Date Thursday, November 3O, 2017 You must show all of you work. Answer must be provided in the spaces given; no points will be allotted for answer given elsewhere. Note that the coordinate system origin is located at the intersection of the neutral axis of the beam and the wall. All answers must be in terms of the problem "givens (qo. L. E.G.v,b,h, and x) x-0 E, G,v Step 1: Determine the reaction forces at the wall Free-Body Diagram 2 (pts) (1 pts) (1 pts) Describe the point about which you are taking the moment (1 pts) (1 pts) (1 pts) MA

Explanation / Answer

Since the beam is cantilver beam,vertical reaction force at wall=total vertical load applied = 0.5*qo*L

moment reaction at wall = moment at wall due to appled load = 0.5*qo*L*L/3 = 0.5*qo*L2/3

Shear force expression for 0<x<L

Shear force at x =V(x)= 0.5*qo(L-x)

moment at x =M(x)= 0.5*qo(L-x)2/3
