A left-turn movement has a maximum arrival rate of 200 veh/h. The saturation flow of this movement is 1400 veh/h. For this approach, the yellow time is 4 seconds, all red time is 2 seconds and total lost time is 3 seconds. The cycle lenght is 120 seconds. What minimum displayed green time must be provided to ensure to ensure that the queue in each cycle clears, and what is the total delay per cycle and delay per vehicle for this green time?(Assuming D/D/1 queuing)
At all other times, the wind velocity is zero. Determine for each case the ration of the total energy available from the wind to the total wind energy available at the mean velocity operating continuously
Three shafts and four gears are used to form a geartrain which will transmit 7.5 kW from the motor at A to a machine tool at F. (Bear- ings for the shafts are omitted from the sketch.) Knowing that the frequency of the motor is 30 Hz
Find the stress induced in the aluminum rod if, after the gap is closed, the two segments are welded together, and then a leftward force is applied of the same magnitude needed to close the gap. Assume the rod segments remain aligned during loading.
The subsoil at the site is a thick layer of soft alluvial river silts and sands, the bearing capacity of the silt has been found to be in the region of 80 kN/m2. There is a high ground water table present.

To apply shock loading to an artillery shell, a 20-kg pendulum A is released from a known hight and strikes impactor B at a known velocity Vo. inpactor B then strikes the 1-kg artillery shell C.
The pins on the frame at B and C each have a diameter of 0.25 in. If these pins are subjected to double shear, determine the average shear stress in each pin.
