3. Calculate φMn. fy = 60000 psi and f’ c = 3500 psi in a 30" x 14" rectangular beam with 4 #11 (6.25 in^2) bars in the bottom, 3" clearance between the bottom and the first row of rebar at the bottom, and 2.5" between the top wall of the beam and top row of rebar 2 #9 (2 inch^2) at the top. The space between the bars at the top and top bottom ones is 21.5 inches.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
