No, David! is a 1998 children's picture book written and illustrated by David Shannon and published by Scholastic Inc. Shannon wrote a story by himself at five years old, and later in his life, he found this story and decided to publish it after re-writing this original work.
The Hotchkiss drive uses two universal joints, which has the effect of canceling the speed fluctuations and gives a constant speed even when the shaft is no longer straight [citation needed]. V8-powered models of the 1963 through 1966 AMC Rambler used a double-Cardan constant velocity joint to eliminate driveshaft fluctuations, though six ...
For rod length 6" and crank radius 2" (as shown in the example graph below), numerically solving the acceleration zero-crossings finds the velocity maxima/minima to be at crank angles of ±73.17530°. Then, using the triangle law of sines, it is found that the rod-vertical angle is 18.60639° and the crank-rod angle is 88.21832°. Clearly, in ...
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to ...
Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object. (Velocity is on the y-axis and time on the x-axis. Multiplying the velocity by the time, the time cancels out, and only displacement remains.)
In contrast to an average velocity, referring to the overall motion in a finite time interval, the instantaneous velocity of an object describes the state of motion at a specific point in time. It is defined by letting the length of the time interval Δ t {\displaystyle \Delta t} tend to zero, that is, the velocity is the time derivative of the ...

The Hotchkiss drive is a shaft drive form of power transmission. It was the dominant means for front-engine, rear-wheel drive layout cars in the 20th century. The name comes from the French automobile manufacturer Hotchkiss , although other makers, such as Peerless , used similar systems before Hotchkiss.
