Your bicycle has 10 gears, from low (easiest to pedal) to high (hardest to pedal). When you first start peddling, you usually use a low gear to accelerate from standing and then shift to a higher gear when you are at a high cruising (ground) speed so that you are always pedalling against the same resistance. One morning you forget to shift down and you try to start in a very high gear. Despite the fact that you usually go fast in high gear, you can't get anywhere at all. The next day you remember to start in low gear, but you forget to shift up. So you ride to school at the same ground speed as usual but in low gear all the way. Despite the fact that there is less resistance to pedalling in the low gear, your legs get more tired than usual.  Using you knowledge of force and resistance explain why they are more tired? Explain which skeletal fibers will be utilized in this case?

I don't know how to solve #5

The rotation axis of the uniform cylinder is constrained by a frictionless slot. The cylinder is at rest when it is lowered onto the conveyor belt, which has a constant translational velocity of 20.0 ft/s. The coefficient of friction between the belt and the cylinder is 0.400.a) Calculate the maximum angular velocity of the cylinder.b) The distance traveled by the belt during the time the cylinder is accelerating to its maximum angular velocity

Question In the image. Please explain with steps to explain how you got the answer.

In a pin joint 4 bar mechanism, fixed Link 1= 600 mm, Link 2 and Link 3= 360 mm and link 4 = 300 mm. The angle between link 1 and link 2 is 30°. The crank link 2 rotates uniformly at 240 rpm. a) Draw the space diagram of the link above. b) Locate all the instantaneous centers using Aronhold Kennedy's Theorem. c) Calculate the angular velocity of link 3.

Either solve all parts or none ....    Vll definitely upvote

Scenario 1 Your boss, Melon Usk, wants you to determine the acceleration of his new car. The details of the car are as follows: The car's total mass is 1500 kg The motor outputs a constant torque of 300 Nm The drive train has a gear ratio of 10:1 to the drive axle Prior to any gearing, the motor and drivetrain have a moment of inertia of 0.5 kg m². The four tires are 0.6 m in diameter. A single set of final gear, drive axial, and tire has combined moment of inertia of 0.6 kg m². Not knowing how to proceed, you e-mail your favourite ex-instructor, Frank. He is very busy but draws you the following: ● ● ● ● ● ● Motor ● FT+ IM = 0.5 kg. m² TIN = 300Nm TIN Final Gear + Wheel Wheel RG Final Gear C Rw Fw Iw = 4(0.6 kg m²) = 2.4kg. m² RG = 10R Rw = 0.3m Car Fw m = 1500kg y x Frank also notes the following: You can treat all four tires, axels, and final gears as a single entity. The moments of inertia will add together but the radius will remain the same. You do not need to know the complex…

Hello, could you please help. i need to work out the holding torque, thanks
