Question

Problem 1 Consider the cantilever beam shown below. This beam is loaded with a downward pointing point load that moves horizontally along the top of the beam. The position of the load from point A, the fixed point, is denoted by x. An influence line diagram showing the internal moment at point B as the load moves across the beam is also shown below 1 kip x, Position of load from Point A (ft) 24 Moment at Point B (kip-ft)/kip 12' 24' -12 a) Using a couple sentences, explain in words how you would use the provided influence b) Determine the moment at B when an upward pointing point load of 7 kips is 18 ft from Nate: You do not need to calculate and plot an inf luence line diagram, it is already given to you line diagram to determine the moment at B given a load P at position % on the beam. the fixed end

Answer 1

if you have any doubts pls comments bellow......pls rate positive rateings.....

thank you........
