Question
Chapter 18, Problem 1RQ
To determine
Mention the strokes of a four-stroke cycle.
Expert Solution & Answer
Explanation of Solution
The engine cycles are determined by the total number of piston strokes needed to finish the cycle. During each stroke, the crankshaft completes rotation of
The strokes of the four-stroke cycle are as follows:
- Intake stroke.
- Compression stroke.
- Power stroke.
- Exhaust stroke.

Question 1
The engine of a 3500-N car is generating a constant power of 50 hp (horsepower)
while the car is traveling up the slope with a constant speed. If the engine is
operating with an efficiency of € 0.8, determine the speed of the car. Neglect
drag and rolling resistance. Use g 9.81 m/s² and 1 hp = 745.7 W.

Question 2
A man pushes on a 60-N crate with a force F. The force is always directed downward at an angle of 30°
from the horizontal, as shown in the figure. The magnitude of the force is gradually increased until the crate
begins to slide. Determine the crate's initial acceleration once it starts to move. Assume the coefficient of
static friction is μ = 0.6, the coefficient of kinetic…
