Problem #1 (20 points): Two forces are applied to the end of a solid rod depicted in figure 1.
These forces cause internal forces and moments on a cut section 8 in. from the wall, in the
directions shown in figure 2. The rod has a circu
Problem #1 (20 points): A 3 mm diameter cord (Ec = 7 GPa) is covered with a 0.5 mm plastic
sheath (Es = 14 GPa) and subjected to an axial tensile load. The cord is limited to a normal
stress of 15 MPa, and the sheath can withstand a nor
Problem #1 (35 points): A steel cantilever beam is subjected to a triangular distributed load, as
shown. The beam is fixed to the wall at point A. Assume E = 200 GPa and I = 150 106 mm4.
(a) The deflection at point B.
Problem #1 (35 points): A steel beam 12 ft long is simply-supported at its ends and carries a
uniformly distributed load of 1 kip/ft over its entire length. The beam has a T-shaped cross
section with the neutral axis 2.625 in below the
Problem #1 (20 points): The aluminum tube AB has a hollow, rectangular cross section with a
thickness of 3 mm, and is supported by pins and brackets at the ends. The constraints produce a
pinned-pinned condition about the z-axis, and a
Problem #1 (20 points): The steel bar shown below has a width W = 60 mm and a thickness
t = 5mm. The circular hole on the left has a diameter d = 10 mm, and the notches on the
right each have a radius r = 5mm. The distance between the n
Problem #1 (25 points): A state of plane stress is shown on the element below.
(a) Construct Mohrs circle for this stress state. Clearly label
all important points.
(b) Using Mohrs circle, determine the principal stresses and
