Problem 20.4 A four-cylinder gasoline engine has an efficiency of 0.22 and delivers 170 J of work per cycle per cylinder. The engine fires at 27 cycles per second. Part A Determine the work done per second. Express your answer to two significant figures and include the appropriate units. ANSWER: Part B What is the total heat input per second from the gasoline? Express your answer to two significant figures and include the appropriate units. ANSWER: Он Part C If the energy content of gasoline is 130 MJ per gallon, how long does one gallon last? Express your answer to two significant figures and include the appropriate units. ANSWER:
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
