What is the gear ratio of the following gear train? 20 teeth input 80 teeth output

A gear box contains 3 sizes of gears, 8 tooth, 32 tooth, and 64 teeth. What is the gear ratio when the 8 tooth gear drives the 32 tooth gear?

Using the data below, calculate the following for all gear settings and list the results in a table form: The speed ratio of the MM245 Automotive gearbox. The input and output torque. The input and output power. The efficiency of the gear system. Gears Input Speed (rpm) Output Speed (rpm) Input Torque (N.m) Output Torque (N.m) 1 322 97 2,67 0,72 2 320 168 3.05 1,23 3 311 238 4,24 1,83 4 297 297 5,95 2,36 5 280 334 7,36 2,80   The moments of inertia of the parts attached to the input shaft A is 0.019 kgm2 and that of the parts attached to output shaft B is 0.1 kgm2. If input shaft A exerts a constant torque of 7.27 Nm and is geared to output shaft B, calculate the following:   The gear ratio gives the maximum angular acceleration of output shaft B. The corresponding angular acceleration of each shaft.

first and last gear having teeth 30 and 5C respectively of a simple gear train. What will be the train value and speed ratiorespectively if first gear is driving gear

The radial distance measured from the pitch circle of a gear to the bottom of the gear tooth is known as the addendum of a gear.   Select one: True False

A system of 5 gears (gear A, B, C, D, E) with the number of teeth 20, 25, 35, 26 and 34, respectively. Gear A has a rotational speed of 600 rpm counterclockwise. a) Determine the direction and magnitude of the rotational speed for each gear (gear B, C, D, E) b) Determine the transmission number (speed ratio)

A gear with 96 teeth revolves at 250 RPM and drives another gear 500 RPM. 19.48 teeth How many teeth are on the driven gear?

Technician A says that if a single idler gear is used to obtain reverse gear, its size and number of teeth must be used to calculate gear ratios. Technician B says that an idler gear is often used for reverse gear because it causes the output shaft to rotate in the reverse direction of the input shaft. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor B

What is the gear ratio found in the gear train of most indexing heads?

Number of Teeth on Gears A, B, C, D, E and F are 40, 132, 50, 120, 50 and 116 respectively. Gear A rotates Clockwise and is connected to a motor spinning at 900 RPM. What is the RPM and rotational direction (Clockwise/Anticlockwise) of various gears, and the final output RPM and rotation direction on shaft of gear F? What is the overall speed reduction of the drive train?
