I need the answer to the rest of the questions
m
The beam is supported by a pin at point A and a roller at
kN
point B. A distributed load of W₁ = 8 -and an applied
force of F₁ = 12 kN are applied to the beam. The beam has
an allowable bending stress of allow = 6 MPa. Neglect the
weight and thickness of the beam.
Take the origin for all functions to be at A., i.e. start at the
left and go right. Must use positive sign convention for V and
M.
