Homework Statement
A fair ground ride comprises of a car, connected to an arm, secured to the main driver by a pin. It rotates about a vertical axis.
when operational:
a) what type of stress is experienced by the pin?, and what type of stress is experienced by the arm?
b) if the max allowable stress in the pin is 15MN/m²; the pin is 25mm diameter, determine the max force F that the car should exert on the pin.
c)if the loaded mass of the car is 200Kg and the radius from the axis of rotation to the centre of mass of the car is 8m determine the angular velocity of the car about the axis of rotation which will give rise to a stress of 12MN/m² in the pin.
I know its a lot to ask but I've really been tearing my hair out over this question as i don't have an example to work from so any help on this would be great .. an example for me to work off would be even better. Thanks
