Afreight train and a passenger train share the same rail track. the freight train leaves station a at 8: 00 a. m. the train travels at a speed of 45 km/h for the first 10 minutes and then continues to travel at a speed of 60 km/h. at 8: 35 a. m., the passenger train leaves station a. the pas¬senger train travels first at a speed of 75 km/h for 5 minutes and then continues to travel at a speed of 105 km/h. determine the location of the siding where the freight train will have to be parked to allow the faster passenger train to pass through. as a safety precaution, it is determined that the time headway between the two trains should not be allowed to fall below 5 minutes.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
