The load per foot of beam length varies as shown. For x = 18 ft, the unit load is 601 lb/ft. At x = 0, the load is increasing at the rate of 51 lb/ft per foot. Calculate the support reactions at A and B. The reactions are positive if upward, negative if downward. [Answer: RA = 2280 ft, RB = 4080 lb]
1. Below on the left you can see a cantilever beam (of structural steel, E = 210 GPa), which is fixed to a wall at C and
loaded by a force F=6kN at an angle a=45°. The magnitude and angle of the force as well as dimensions a=2.5m and
