Question

A simply supported beam, 3m long, 50mm wide by 100mm deep, carries a uniformly distributed of 1200 N/m over its entire length. Determine the following:

1. Value of R1

2. Value of R2

3. Value of Max. V

4. Value of Max. M

5. Value of I

6. Maximum value of shearing stress τ

7. Maximum value of flexural σ

Answer #1

1. As the beam is simply supported than it is symmetric so the reaction at both supports is same that is -

2.

3. Maximum shear force will occur at supports -

4. Maximum moment will occur at mid span of the beam -

5. 6.

Maximum shear stress for rectangular beam is -

7.

Maximum value of flexural stress -

A simply supported beam is 3 m long. It carries a uniformly
distributed load of 6 kN/m throughout its span and a concentrated
load of 15 kN at a point 2 m from the left support. Assuming that
the beam has a rectangular shape whose width and depth are 150 mm
and 250 mm, respectively. Determine the maximum flexural stress in
MPa developed in the beam.

overhanging beam is simply supported at san of 13m and carries of
point load of 4000N 3m from right support the left overhangs is 3 m
away from left support and has a point load of 5000N. the right
overhang is of 4m carrying UDL of 200N per meter for entire
rightover . draw shear force and bending moment diagram . calculate
the maximum bending moment.

A simply supported beam spans 30 ft. and carries a uniformly
distributed dead load of 3.5 kip/ft,excluding the beam self-weight.
Also, in addition, a concentrated dead load of 15 kips and a
concentrated live load of 25kips, both act at the center of a 30 ft
span.Select the lightest-weight W-Shape to carry the load(A992
steel). Use LRFD method.

A simply supported beam spans 20 ft and carries a uniformly
distributed dead load of 0.8 kips/ft including the beam self-weight
and a live load of 2.3 kips/ft. Determine the required plastic
section modulus and select the lightest weight Wshape to carry the
moment. Consider only the limit state of yielding (Zone 1) and use
A992 steel. Design by (a) LRFD and (b) ASD.

A simply supported beam spans 20 ft. and carries a uniformly
distributed load of 1 kip/ft,including the beam self-weight, and a
live load of 2.5kip/ft. Determine the minimum required plastic
section modulus and select the lightest-weight W-Shape to carry the
moment (A992 Steel). Use LRFD method.

A 1200 mm deep by 750 mm wide post-tensioned simply supported
beam is shown below. The beam spans 12.0 m and is subject to a
superimposed dead load of 50 kN/m and a live load of 35 kN/m. Both
the superimposed dead load and live load are applied after transfer
(after stressing has taken place). The tendon is located at the
mid-height of the beam at each end, and its centreline sits 50 mm
from the base at midspan. The...

A propped beam of 2m span carries a uniformly distributed load
of 100kN/m spread over its entire length. Calculate the maximum
deflection in mm. EI is constant. Use the area moment method.
