determine the Allowable Stress Design (ASD) reference and adjusted design values for the following members and loading conditions. All members are No. 2 Hem-Fir and are fully braced to prevent lateral-torsional buckling. Bending occurs about the strong axis.
a. Roof joists are 2×10 at 16 in o.c. which directly support the roof sheathing. Loads are (D+S).
b. A 6×14 carries an equipment load that can be considered a permanent load.
c. Purlins in a roof are 4×14 at 8ft o.c. Loads are (D+Lr)
d. Floor beams are 4×6 at 4ft. o.c. Loads are (D+L). High-humidity conditions exist, and the moisture content may exceed 19 percent.
The uniform steel shaft has two gears attached to it at B and C, two frictionless bearings, and the motor. The motor generates 15kip·in and the gears consume 10kip·in and 5kip·in. Find the diameter of the shaft if the maximum rotation between A an..
