A7.5 – The inversion of a slider-crank mechanism shown below is driven by link 2 at w, = 20 rad/s ccw. Bydrawing a velocity polygon and considering any constraints, estimate

the velocity of point P and the angularvelocities of links 3 and 4. \mathrm{R}_{\mathrm{BA}}=40 \mathrm{~mm} \mathrm{R}_{\mathrm{CA}}=35 \mathrm{~mm} \mathrm{R}_{\mathrm{BP}}=142 \mathrm{~mm} \angle C A B=75^{\circ}
