6-lane freeway with FFS = 70 mph; one-lane on-ramp with FFS of 50 mph; one-lane off-ramp with FFS of 35 mph; distance between ramps = 2,000 ft; acceleration lane = deceleration lane = 350 ft; rolling terrain; 15% heavy vehicles on freeway; 10% heavy vehicles on ramps; Freeway flow rate (upstream of on-ramp) = 3,700 veh/hr; on-ramp flow rate = 700 veh/hr; off-ramp flow rate = 300 veh/hr; PHF = 0.96 Required:
Find LOS and speed within the ramp influence area and the outer freeway lanes (on-ramp is followed by off-ramp)

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
