Question

Determine the bending moment acting at each of the following locations:(a) x = 11.0- ft (i.e., just to the left of point B)(b) x = 11.0+ ft(i.e., just to the right of point B)(c) x = 14.00 ft (i.e. at point C)(d) x = 19.5 ft

Answer 1

See explanations

Explanation:

Determine the shear force acting at each of the following locations:

(a) x = 0+ ft (i.e., just to the right of support A)

(b) x = 3.0 ft

(c) x = 8.0 ft

(d) x = 12.0– ft (i.e., just to the left of D)

(e) x = 12.0+ ft (i.e., just to the right of D)

(f) x = 15.5– ft (i.e., just to the left of support E)

Use the graphical method to determine the bending moment acting at B (i.e., x = 3.0 ft). When entering your answers, use the bending moment sign convention.

The shear-force diagram crosses the V = 0 axis between points B and C. Determine the location x (measured from A) where V = 0 kips.

Calculate the maximum bending moment (i.e., either positive or negative) that occurs between points B and C. When entering your answers, use the bending moment sign convention.

Use the graphical method to calculate the bending moments at:

(a) point C.

(b) point D.
