A cantilever beam AB has a rectangular cross section and is loaded by a force P at an angle α that acts at the centroid of the cross section. Two strain gages are placed at point C, which is at mid-height of the beam. Gage D measures the strain in the horizontal direction and gage E measure the strain at an angle β. The measured strains are εD = 145 x10-6 and εE = 165 x10-6, respectively. Find the force P and angle α, assuming the material is steel. The self weight of the beam can be neglected.

Use the given values of ν = 1/3, β = 60°, b = 20 mm and h = 175 mm.
To prove that a system islinear or time-invariant, the property must be demonstrated for all possible input/output pairsand all delays. On the other hand, to prove that a system is not linear or not time-variant,the property can be demonstrated with ..
Select the beam dimensions and reinforcement for a balanced section if the beam sustains a moment as a result of dead load of 60 kip-ft and a moment as a result of live load of 90 kip-ft
After drawing a free body diagram, how do you determine what the forces are in the Ax, Ay directions, etc. without being given any numbers
It leaves the pump through a 4-in-diamter pipe at 15 psi. Assuming that the suction and discharge sides of the pump are at the same elevation, find the horsepower delivered to the water by the pump.
The steam flow rate entering the pipe is 2500kg/hr. Due to heat loss from the pipe to the surrounding air (at 25 C) 20 kg/hr of condensate is formed in the pipe and removed at the end of the pipe.
