Question

! Required information Know that the beam AB is an 58 * 18.4 rolled shape and that wo = 4.45 kips/ft, L = 9 ft, and E= 29 * 106 psi. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. WO B C Lui S -L/2 -L/2 Determine the slope at A.
