Problem 4-9a: The link lengths and offset (a, b, and the value of θ2 for an offset crank-slider linkage are defined as 1.4 in, 4 in, and 45°, respectively. Draw the scaled linkage and graphically find all possible solutions (both open and crossed) for angle θ3 and slide position d.
Problem 4-10a: Repeat Problem 4-9a, except solve by the vector loop method.
