1.A 2650-lb car is traveling at sea level at a constantspeed. Its engine is running at 4500 rev/min and is producing 175 ft-lb of torque. It has a drivetrainefficiency of 90%, a drive axle slippage of 2%, 15-inch–radius wheels, and an overall gear reduction ratioof 3 to 1. If the car’s frontal area is 21.5 ft 2 , what is itsdrag coefficient?

2.Two steel plates were constructed in warm weather. Due to temperature change, a 1/32" hole mismatching occurred. What is the pulling force, in lbs, to be applied for one of the plates to match the two holes The plate length is 3 ft (from the left end to the hole) and its cross section is 1/8" x 1".
