举一反三
- It is held in the crankcase in the cylinder block and converts the reciprocating motion of the pistons into a rotary motion for the drive wheels．
- The reciprocating motion of the pistons is changed to rotary motion as the crankshaft spins. 这句话的意思是旋转运动就转化为活塞的往复直线运动。
- The reciprocating motion of the pistons is changed to rotary motion as the crankshaft spins. 这句话的意思是旋转运动就转化为活塞的往复直线运动。 A: 正确 B: 错误
- Which of the following is NOT an example of accelerated motion? A: Vertical component of projectile motion B: Circular motion at constant speed C: A swinging pendulum D: Earth’s motion about sun E: Horizontal component of projectile motion
- The linear motion of a diesel engine piston is converted to the rotary motion required to drive gears， propeller shafts， and generators by the （）.
