A rigid pavement is being designed with the same parameters as used in Problem 4.5. The modulus of
subgrade reaction is 300 lb/in3 and the slab thickness is
determined to be 8.5 inches. The load transfer
coefficient is 3.0, the drainage coefficient is 1.0, and
the modulus of elasticity is 4 million lb/in2. What is the
design modulus of rupture? (Assume that any
parameters not given in this problem are the same as
those given in Problem 4.5

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

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
