We would like to bolt the cantilevered beam to the column using a bolt pattern with two bolts. We are considering two possibilities: The bolts will be arranged in-line vertically, 5 inches apart, centered in the 6x6 in box, or, the bolts will be arranged in-line horizontally, 5 inches apart, centered in the 6x6 in box. Determine if one of the arrangements is preferable. Prove your point. You can do this by calculating the worst shear stress on a bolt in each case and selecting the case with the lesser shear stress.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

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