Flow on a particular day is approximately 2,000 vph. at 10: 00 am, an incident occurs which reduces capacity to 1,600 vph. the incident is cleared 45 minutes later and the flow returns to the normal capacity of 2,400 vph. (a) draw the fundamental diagram.

(b) draw a time-space diagram that shows the evolution of traffic.

(c) assuming there are no ramps upstream, what are the speeds of the forming and clearing shock waves of the queue upstream of the incident?

(d) assuming that the demand does not change, compute the duration in which the maximum flow of 2,400 vph is observed at the location of the incident.

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
