1.A 3-point bending test is performed on a 10 mm diameter rod of Silicon Carbide. The distance between the supports is one foot. If the load at fracture is 10,000N, what is the flexural strength of the rod? How much bending (deflection) did the rod undergo just before failure?
2.An open channel with a trapezoidal configuration with side batters 1V:3H is to be designed to carry 1.0m^3/s with a bedslope of 0.0065. The channel is lined with concrete with manning's n of 0.011. Find the most efficient cross section.
