What would be the percent change in deflection if a solid
rectangular beam has its unsupported length changed from 30 inches
to 36 inches? SHOW YOUR CALCULATION. What does
this tell you about the importance of unsupported beam length in
structural design?
24' Steel beam has deflection L/300. Compression flange has
lateral bracing. Beam has a uniformly distributed live load of 800
pounds per linear foot. Dead load is 50 PLF.Select best A992 W
shape for the beam.
Explain the behavior of rc beam (load-deflection or
Moment-curvature) under the flexural loading highlighting different
stages of loading till failure; i.e. un-cracked section, cracked
section, service condition, yielding and ultimate loading
condition.
(a) calculate the magnetic field, B required to produce a
deflection of 0.25 rad in Thomson’s experiment, assuming the values
V= 205 V, length, L = 4.9 cm, and d= 1.5 cm. (b) Find the
horizontal velocity vx for this case.
Calculate the minimum prestressing force required for Beam 1
knowing that the beam has a cross sectional area of 200 × 500 mm
and an allowable stress of 0.3 N/mm2 . External Load applied in
Tons/m is 150
Use the Divergence Theorem to calculate the surface integral S F
· dS; that is, calculate the flux of F across S. F(x, y, z) = x4i −
x3z2j + 4xy2zk, S is the surface of the solid bounded by the
cylinder x2 + y2 = 1 and the planes z = x + 8 and z = 0
