Analytic. Matrix Method for Velocity Analysis

1) With the crank 2 at ?₂=60^o, at t=0.1666 s, write the equations for positional analysis.

2) Solve the system of equations and determine the elements of Latin Matrix L

4) Using the analytic method by solving the system of equations:

1. Calculate the degree of undermines “n”;

2. Choose a rational analysis scheme for method of force

3. Calculate diagrams from unit loads and actual forces;
