Question

At the instant ?=30?, the frame of the crane is rotating with an angular velocity of ?1=1.5rad/s and angular acceleration of ??1=0.5rad/s^2, while the boom AB rotates with an angular velocity of ?2=0.5rad/s and angular acceleration of ??2=0.25rad/s^2

Part A

Determine the velocity of point B at this instant.

Enter the x, y, and z components of the velocity separated by commas.

Part B

Determine the acceleration of point B at this instant.

Enter the x, y, and z components of the acceleration separated by commas.

1.5 m 12 m CO2, CO2

Explanation / Answer

From the given data

Velocity = 3i+5j-3k

Acceleration=5j+9k

Acceleration = sqrt(25+81)
