Automotive true or false questions?

• True or False 1. One horsepower will produce 33,000 foot-pounds of work in one second. 2. Most cars have drum brakes on the front wheels, and disc brakes on the rear wheels. 3. Most cars have the same kind of suspension in the front end as they do in the rear end. 4. A multi-purpose fire extenguisher should be readily available when working on a car. 5. Most nuts and bolts on a new car require SAE (inch) sized tools. 6. You will need a manufacturers service manual to perform most basic under-the-hood mainteance on your car. 7. During the four stroke cycle of an individual piston, the crankshaft completes two revolutions, and the camshaft completes one revolution. 8. Late model cars with high performance engines often have two intake and two exhaust valves per cylinder. 9. When rings and cylinders in a car engine wear out, compression pressure is reduced, and a thick black smoke is produced. 10. When compression is being lost mainly through the valves then a complete engine overhaul may not be necessary. 11. The engine bearings that are fitted between the crankshaft rod journals and the connecting rods are called rod bearings. Please help me with these questions. Ten points to best answer. thank you!! :)

• Answer:

  1. F, 550 ft lbs per sec. 2. F typically disk on front, drum on rear 3. F typically independent coil struts and track arms in front, leaf springs in rear. 4. T drop lights and gasoline drips are fire hazards 5. F metric now 6. T hard to even tighten a belt now without a manual 7. T 8. T 9. F bad compression burns oil for thin blue or brown smoke, thick black is excess gasoine 10 T valved are entirely in the removable head. 11 T
