Using LRFD, select a 30-ft-long W section of A992 steel with a
nominal depth of 10 in (a W12) to support a tensile service dead
load PD=130kand a tensile service live load PL=110k. In addition,
the section is to comply with the slenderness ratio limit from AISC
D1 to prevent sag of the member. As shown in the figure below, the
member is to have two lines of bolts in each flange for 7/8-in
bolts (at least three in a...

Determine the allowable axial compressive load for a 25-foot
long A992 W8X40 structural steel column using the AISC procedure as
indicated in your textbook. The bottom of the column is fixed, an
the top is pinned. Use the material properties and dimensions as
indicated in the appendices of your textbook.

A uniform steel beam of length 5.00 m has a weight of 4.50 ✕
10^3 N. One end of the beam is bolted to a vertical wall. The beam
is held in a horizontal position by a cable attached between the
other end of the beam and a point on the wall. The cable makes an
angle of 25.0° above the horizontal. A load whose weight is 12.0 ✕
10^3 N is hung from the beam at a point that...

A steel wire with a cross-section area 2.5X10^-3 m2 and a length
of 10 m is used to pull a truck on the road. The truck is 10 tons
and the friction coefficient between the tires and road is
0.25N/kg. Steel has a Young’s modulus 250MPa.
Suppose this wire contain surface cracks. Determine the largest
linear size of the surface crack so that the wire will not fail due
to fracture in this application. Kc = 0.1 MPa m^0.5

You are measuring a line with a steel tape that has a
standardized length equal to 100.000 feet and a weight of 2.25 lb.
Three full tape lengths and one partial length were used when
making the measurement, resulting in a recorded length of 389.28
ft. The tape was supported at ends only and a pull of 12 pounds was
used. What is the distance after being corrected for sag?
CORRECT ANSWER IS 389.82ft

Given: A short
cylinder of steel has a diameter of 150 mm and length of 500 mm. It
comes out of a heat treatment process at a uniform temperature of
200oC and is plunged into an unstirred bath of oil at a
temperature of 20oC.
Find:
Considering heat loss from only the
cylindrical surface (ignore the ends), which orientation would cool
more quickly? One orientation is for the axis to be parallel to
gravity and the other perpendicular to...
