Question

Member AB has an angular velocity of
3.00 rad/s counterclockwise and an
angular acceleration of 10.0 rad/s2
counterclockwise in the position shown.
Calculate magnitude and direction of
the angular acceleration of Member EC.

**Problem Statement:** Member \( AB \) has an angular velocity of \( 3.00 \, \text{rad/s} \) counterclockwise and an angular acceleration of \( 10.0 \, \text{rad/s}^2 \) counterclockwise in the position shown. Calculate the magnitude and direction of the angular acceleration of Member \( EC \). **Diagram Explanation:** - The diagram shows a mechanical system with members labeled \( A \), \( B \), \( C \), \( D \), and \( E \). - Member \( AB \) is vertically oriented and serves as a rotating link, pinned at point \( A \). - Member \( EC \) is inclined and supported horizontally at point \( C \) with a connecting link to \( B \). - Point \( D \) is a fixed pivot, and the distance from \( C \) to \( D \) is specified as \( 4" \). - Distance from \( A \) to \( B \) is \( 5" \). - The vertical distance from \( A \) to the line passing through \( B \) is \( 4" \), and from \( B \) to \( E \) is \( 3" \). - The horizontal distance from \( A \) to \( C \) is \( 10" \). **Objective:** To find the angular acceleration of Member \( EC \) based on given parameters and relationships in the assembled mechanism.
