Question

i want just (F)

2. (40 points) In the engine mechanism shown in fig. 2, the crank AB has a constant clockwise angular velocity of 2000 rpm.And the connecting rod is a uniform, slender rod whose center of mass is in its geometric center G. For the crank position shown determine l 8 in 3in Figure 2: Problem 2 (a) (2.5 points) The velocity of B (b) (5 points) The angular velocity of the connecting rod BD, and the velocity of the piston p (c) (2.5 points) The acceleration of B (d) (5 points) The angular acceleration of the connecting rod BD and the acceleration of point D (e) (5 points) The acceleration of point G (f) (20 points) If the connecting rod weighs 4 lb, and the piston P weighs 5 lb, and the moment of inertia of a rod about its center of mass is given by IG = ,12, determine the forces in the connecting rod at pi B, as well as the normal reaction on the piston P (g) (Bonus 5 points) Verify your answers for parts a and b using instantaneous center of velocities.

Answer 2

I just want e The crank AB has a constant clockwise angular velocity of 2000 rpm. For the crank position indicated, determine (a) the angular velocity of the connecting rod BD, and (b) the velocity of the piston P.
