Consider the basketball pole and hoop modeled in two dimensions below. the base of the pole is cemented to the ground. prof. juarez and prof. kersh are still playing with jordan and try again to block a shot and land on the hoop with forces fj and fk at point a. they begin to worry that the long winter has taken it’s toll on both their diets and the material strength of the pole.

given the following:

|fj|=500.31 n

|fk|=431.64 n

alpha=23 degree

a=2 m b=3 m c=1.8 m

determine the internal loads acting on the upper portion of the pole at point b.
hint: make sure your reactions at b follow the sign convention for internal forces.

normal force at b = ? n

shear force at b = ? n

bending moment at b = ? nm

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
