I need help writing a Matlab computer program for the following problem. If you could help me id greatly appreciate it. I will rate. Thank you.

INSTRUCTIONS
Consider the diagram shown below. It depicts a simple bridge and a HS 15-44 truck live load.
Write a program that will compute and visualize the influence lines of bending moment and
shear force at points C for the two cases below, due to the influence of moving live load HS 15-
44. Note that A1, A2, A3, and A4 are support points. Take L1= 20 ft, and L2= 15 ft, 11 = 20 ft,
12 = 14 ft, and F=12k. Note that there are hinges at B1 and B2. State any reasonable
assumptions.

A cantilever of length 3L has section second moments of area I, I, and I, referred to horizontal and vertical axes through the centroid of its cross section. If the cantilever carries a vertically downward load W at its free end and is pinned to a support which prevents both vertical and horizontal movement at a distance 2L from the built-in end, calculate the magnitude of the vertical reaction at the support. Show also that the horizontal reaction is zero. Ans. 7 W14.
