The simply supported joist is used in the construction of a floor for a building. In order to keep the floor low with respect to the sill beams C and D, the ends of the joists are notched as shown. If the allowable shear stress is tallow = 350 psi and the allowable bending stress is sallow = 1500 psi, determine the height h that will cause the beam to reach both allowable stresses at the same time. Also, what load P causes this to happen? Neglect the stressconcentration at the notch.
A laminated spring Im long is built in 100 mm x 10 mm plates. If the spring is to carry a load
of 10 kN at its centre, determine the number of plates required for the spring. Take allowable
bending stress as 150 MPa.
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
m
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.
