The hanger assembly is used to support a distributed loading of w=16kN/m. Determine the average stress in the 12-mm-diameter bolt at A and the average tensile stress in rod AB, which has a diameter of 15 mm. If the yield shear stress for the bolt is ty = 180 MPa, and the yield tensile stress for the rod is sy = 275 MPa, determine factor of safety with respect to yielding in each case.
Two bars are used to support a
load P. When unloaded, AB is
125 mm long and AC is 200 mm
long, and the ring at A
has coordinates (0,0). If a load is
applied to the ring at A, so that it
moves it to the coordinate
position (6.25 mm, -18.25 mm),
determine the normal strain in
The bar DBA is rigid and is originally
held in the horizontal position. When the
weight W is supported from D, it causes
the end D to displace downward 0.5 mm.
The wires are made of A-36 steel and have
a cross-sectional area of 0.8 mm2, and
Est= 210 GPa.
The rigid pipe is supported by a pin
at C and an A-36 steel guy wire AB.
If the wire has a diameter of 5 mm,
determine how much it stretches
when a load of P = 1500 N acts on
the pipe. The material remains elastic.
E = 210 GPa.
“how much it stretches”
What does it mean??
stretch = change in length =dAB
A shear spring is made from two blocks
of rubber, each having a height h, width
b, and thickness a. The blocks are
bonded to the three plates as shown. If
the plates are rigid and the shear
modulus of the rubber is G, determine
the displacement of plate A if a
vertical load P is applied to this plate.
Assume that the displacement is small
so that d = a tan g ag
