10/7,1 ### Bicycle Gear and Speed Calculation ExerciseA bicycle with 19-inch diameter wheels has its gears set so that the chain has a 6-inch radius on the front sprocket and a 3-inch radius on the rear sprocket. The cyclist pedals at 190 rpm (revolutions per minute).**Problem 1: Calculate the Linear Speed of the Bicycle**Find the linear speed of the bicycle in inches per minute (correct to at least two decimal places).- **Answer:** [Input Box] inches/min**Problem 2: Convert the Linear Speed to Miles Per Hour**How fast is the bike moving in miles per hour (to two decimal places)?- **Answer:** [Input Box] mph---### Solution Steps and Explanation1. **Determine the Gear Ratio:** - The front sprocket radius = 6 inches - The rear sprocket radius = 3 inches - Gear Ratio = Front Sprocket Radius / Rear Sprocket Radius = 6 inches / 3 inches = 22. **Calculate the Rear Wheel RPM:** - Pedaling RPM (given) = 190 rpm - Rear Wheel RPM = Pedaling RPM * Gear Ratio = 190 rpm * 2 = 380 rpm3. **Calculate the Linear Speed in inches per minute:** - The circumference of the wheel = π * Diameter = π * 19 inches - Therefore, the Linear Speed = Circumference * Rear Wheel RPM = π * 19 inches * 380 rpm4. **Convert Linear Speed to mph:** - 1 mile = 63,360 inches - 1 hour = 60 minutes - Thus, Speed in mph = (Linear Speed in inches per minute * 60 minutes) / 63,360 inchesThese calculations will allow you to determine the linear speed in inches per minute and subsequently convert that speed into miles per hour. Input your answers in the respective boxes provided.*Remember to use a calculator for precise computation and rounding off to at least two decimal places.*

In the gear train shown gear 3 is carried on arm 5, Gear 3 meshes with gear 2 and gear 4. The number of teeth on gear 2, 3 and 4 are 60, 20, and 100, respectively. If gear 2 is fixed and gear 4 rotates with an angular velocity of 100 rpm in the counterclockwise direction, the angular speed of arm 5 (in rpm) is 4 2 3 5
If Gear C and gear A are having the same pitch diameter gear and gear B is twice (larger) the diameter of gear C. If gear C is turning at the speed of 50 RPM, what would be the Rotational speed of Gear B in RPM. (RPM = revolution per minute)
27. You have the following compound machine. 60 teeth A 40 teeth 20 teeth a. What is the speed of Gear D? We want to adjust the gear train. We can only change out Gear C for a different sized gear. Gear A will continue spinning with 600 rpm. How many teeth b. does our new Gear C need to have so that Gear D spins with 200 rpm?
For the simple gear train below, Gear A is the input gear and rotates at 2500 rpm and Gear D is the output gear for this simple gear train. The number of teeth for each gear is as follows: NA = 116 Teeth, NB = 178 Teeth, NC = 70 Teeth and ND = 120 Teeth Calculate the output angular velocity at Gear D (ωD). Give your answer in rads-1 to the nearest radian.
