Homework 1
1. The cable in the frictionless pulley system shown below has an ultimate force of
500N (Pult = 500N ). Using a factor of safety of 2.0, will it support the loading
shown? If it will, the
SOLUTIONS
A 10ft long beam with a ﬁxed end mounted to a wall supports a distributed load
of 2.0 k/ ft. The other end of the beam is supported by a second 12ft long beam
supported on roller supports. Determine the reaction at the roller supports. Both
beam
SOLUTIONS
Given:
A spherical pressure vessel has an outer diameter of 3 m and a wall thickness of 12 mm. Knowing that for
the steel used 0'3“ 2 80 MPa, E 2 200 GPa, and v: 0.29, determine (a) the allowable gage pressure, (b) the
corresponding increase i

Given:
The beam shown is 2m long and has a wall support at the left end and a pin (not
roller) at the right end. There is an axially distributed load as shown. Other loads
are present. The cross section is 5cm x 200m. At a dista
