Question

At the instant shown, the $12-\mathrm{in}$. crank on the small aircraft landing gear actuation in Figure P7.41 rotates counterclockwise at 12 rpm and accelerates at $3 \mathrm{rad} / \mathrm{s}^2$. Use the relative acceleration method to graphically determine the angular velocity and angular acceleration of the wheel assembly. (FIGURE CAN'T COPY)

Instant Answer

Step 1

The crank has a radius of 12 inches and rotates counterclockwise at an angular velocity of 12 rpm. The angular acceleration of the crank is given as 3 rad/s². Convert the angular velocity from rpm to rad/s for easier calculations. \[ \text{Angular velocity} Show more…
