AI Thread Summary
The discussion focuses on measuring velocity and acceleration in bicycle shock dynamics, specifically for a 100kg rider. Participants suggest using basic dynamics theories, such as conservation of energy and spring constants, to analyze the system. The mention of a four-bar mechanism indicates a potential method for calculating velocities and accelerations through instantaneous centers. However, there is a lack of resources or websites that provide clear methods for these calculations in four-bar linkages. The conversation highlights the need for further guidance on this topic.

Please go thro the link. it shows an animation of bicycle shox.
http://www.santacruzmtb.com/vpp/. click on the animation

Suppose a person of weight 100kg sits on this how can i know the
velociy,accelerations at various points on the bicycle. Can any
basic dynamics theory help in this?
 
Physics news on Phys.org
i may be wrong but you'd probably need the the spring constant ... use conservation of energy ... also need to know how the load is being transferred due the rotation ... i know I'm wrong but i gave it a shot
 
Don't we have a four bar mechanism there. If that is the case u can calculate the velocities and accln using the instantaneous centers method
 
burnhard,
Any website for showing method to find accelerations,velocity in four bar mechanism?

I am sorry I do not know of any good website which shows the methods to find accelerations and velocities in a Four bar linkage. Maybe someone out there can help.

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
