Question: ( 3 0 points ) For the beam below, derive the influence line for: a . the vertical reaction at B b . the shear

(30 points) For the beam below, derive the influence line for:
a. the vertical reaction at B
b. the shear at C
Use the influence line to calculate the greatest absolute value of the shear at C if the beam is loaded by:
a. a 20 kN point load at the free end (2 m to the left of A)
b. a 15 kN point load at C
c. both a 20 kN point load at the free end and a 15 kN point load at C
( 3 0 points ) For the beam below, derive the
