A W8 3 31 rolled-steel shape is used for a column of 21-ft effective
length. Using allowable stress design, determine the allowable
centric load if the yield strength of the grade of steel used is
(a) sigma Y = 36 ksi
(b) sigma Y = 50 ksi.

Use E = 29 * 10 ^6 Psi

A steel ruler (100 mm) is used for measuring the length of a block. The ambient temperature is found likely to vary in between 24 °C and 25 °C. The temperature is likely to be anywhere within these limits. The temperature variation follows square distribution, with expected value to be 24.5 °C. Determine the degree of uncertainty that will be registered when measurement is done using steel scale? CTE = 11.5 x 10-6 / °C

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
