2.34 Determine the resultant of the three forces of Prob. 2.22. Answer T

Example 3.5 In the mechanism shown in Fig. 3.10(a), the crank OA rotates at 60 rpm. Determine the (1) linear acceleration of the slider at B (li) angular acceleration of the links AC, CQD and BD

The pedal and brake drum are illustrated in Figure Q2(b). The 160 mm radius brake drum is attached to a larger flywheel (not shown). The total mass moment of inertia of the flywheel and drum is 20 kg-m? and the coefficient of kinetic friction between the drum and the brake shoe is 0.35. The initial angular velocity of the flywheel is 360 rpm counterclockwise. If the system is to stop in 100 revolutions, determine the vertical force P that must be applied to the pedal C. (Hint: Draw a free-body diagram for the brake drum and pedal, separately and label all the forces)

(b) The mass of the object suspended at G is 100 kg, as demonstrated in Figure Q5(b). Determine the reaction on member CDE at C and E.

A force F = 6980 N acts upon a piston head, as shown in the figure. The gudgeon pin G connects the connecting rod to pin C where it connects to the crankshaft at S in a large military vehicle. Find the moment of the force at S.

I need help with this question :)

Build the following part. Report the volume in mm^3. Assume all dimensions are in mm. A=52 B=19 Your answer should have 0 decimal places needed. Ex: 76,440 10 - 30 B
