Can someone give me some pointers on this question...
Discussion
Hi all,
I'm having a little trouble with my college work at the moment, and was wondering if anyone can give me an equation, or series of equations to get the answer to this question:
A screw jack is 47.5% efficient, and has a thread with a pitch of 3.5mm. The radius of the tommy bar is 350mm. If a force of 120N applied to the tommy bar is necessary to raise a vehicle, what is the mass of the vehicle?
While this may sound silly, I'm really struggling to get my head round it! I'm not bothered about getting answers to the question, more the equations associated with being able to get the answer so I can try and understand it.
Thanks in advance.
