Question
Im giving you the solution. Just replace the numbers with my problem and solve:
The reel of rope has the angular velocity ? = 5 rad/s and angular acceleration ? = 7 rad/s2 .
A) The reel of rope has the angular velocity ? = 5 rad/s and angular acceleration ? = 7 rad/s2 .
B) Determine the direction of the velocity of point A at the instant shown.
C) Determine the magnitude of the acceleration of point A at the instant shown.
D) Determine the direction of the acceleration of point A at the instant shown.
Solution:
Explanation / Answer
Hence the solution for A will be
The IC will be same as .1414m
Hence the Va will be
Va = w IC = 5 * .1414 = 0.707 m
B) THe accelaration is .7 m/s^2
The relative one will be
a = -.7j + .7 i + 2.5 j = .7 i + 1.8 j
Hencre magnitude wuill be
a = 1.93 m/s^2
c) Theta = tan-1 (1.8/.7) = 68.73 degree
