Determine the available column strength of a 10 ft. long WT7x34 (A992) that is braced laterally and torsionally at the ends only, by considering (i) flexural, (ii) torsional, (iii) flexural-torsional buckling. This is a singly symmetric section so for (iii), you can follow Section E4(b) in the Specification.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
