Question

Question 18 A6 ft long A36 steel W12x14 carries a concentrated load as shown. Assume all stresses remain linear elastic. 3 kip A B 3 ft 3 ft The slope at A is most nearly.... 6.51 deg O N/A - there is no slope at A O 0.17 deg 1.03 deg

Answer 1

For A36 steel E= 29000 ksi

For w12x14 beam , I = 88.6 in^{​​​​​4}

For cantilever beam slope at free end

Slope = ( W * L ² ) / (2EI) = 3* (6*12)² /(2*29000* 88.6)

= 0.003 radians = 0.17 degrees.

Answer option C
