Engineering Mechanics - Dynamics Chapter 20 Problem 20-1 The ladder of the fire truck rotates around the z axis with angular velocity ω 1 which is increasing at rate α 1 . At the same instant it is rotating upwards at the constant rate 2 . Determine the velocity and acceleration of point A located at the top of the ladder at this instant. Given: 1 0.15 rad s = 1 0.8 rad s 2 = 2 0.6 rad s = θ 30 deg = L 40 ft = Solution: r 0 L cos () L sin
