A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 2 No. 7 bars. The concrete strength is 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 1.323529 in. and the strain in the reinforcement is εs = 0.038423, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

A flea jumps by exerting a force of 1.20 X 10^-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.500 X 10^-6 N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.00 X 10^-7 kg. Do not neglect the gravitational force.
