1.An alloy is made up of 199.4 lbm copper, 204 lbm zinc, and 4.2 lbm lead? What is the composition, in atom percent, of the Cu-Zn-Pb alloy?
2.Determine the uniform flow depth in a trapezoidal channel with a bottom width of 8 ft and side slopes of 1 vertical to 2 horizontal. The discharge is 100 ft3/s. Manning roughness factor is 0.015 and the channel bottom slope is 0.004.
3.If the 10-lb block passes point A on the smooth track with a speed of va = 5 ft/s determine the normal reaction on the block when it reaches point b.
