A3/8-in × 2-in aisi 1018 cold-drawn steel bar is cantilever to support a static load of 550 lbf as illustrated. the bar is secured to the support using two 3/8 in-16 unc sae grade 4 bolts. assume the bolt threads do not extend into the joint. find the factor of safety for the following modes of failure: shear of the bolt, bearing on the bolt, bearing on the member, and bending of the member. give the overall joint factor of safety.

Aparticle travels in a circular orbit of radius 21 m. its speed is changing at a rate of 23.1 m/s2 at an instant when its speed is 37.2 m/s. what is the magnitude of the acceleration (in m/s? ) of the particle?

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
