The pinion (gear 2 on shaft a) rotates at 635 rev/min clockwise and transmits 1305 W through the idler pair (gears 3 and 4 on shaft b) to the output gear (gear 5 on shaft c). Gears 2 and 3 have a module of 2 mm, and gears 4 and 5 have a module of 3 mm. Pressure angles are all 20 degrees. Solve for the magnitude of the force that shaft b must apply to gears 3 and 4 to maintain static equilibrium in the figure shown here. The figure is not to scale. 187 487

The shaft as shown in Figure 2 below, having an angular velocity of 100 rev/min, is to be balanced by adding masses in the two correction planes, L and R. The three masses are m1= 6 g, m2 = 7 g, and m3 = 5 g. The dimensions are a= 25 mm, b = 300 mm, c = 600 mm, d =150 mm, e = 75 mm, R1 =125 mm, R2 =150 mm, and R3 = 100 mm.

Please draw the figure. Thank you so much.An engine flywheel and a clutch plate are both connected to a transmission shaft. Let the moment of inertia of the flywheel be I1 and its angular velocity ω1, and let the moment of inertia of the clutch plate be I2 and its angular velocity is ω2. The two discs have then been combined by forces which are applied at their axes of rotation so as not to cause any torque. The discs then reached a common final angular velocity after rotational collision. Find the expression for the final angular velocity.
A shaft has three eccentrics of mass 1kg each. The central plane of the eccentrics is 50 mm apart.
