Homework Help: Physics?

Posted by Tony on Friday, December 4, 2009 at 9:38am.

Hi this question is beyond me, so any help = great.

A useful instrument for evaluating fibromyalgia and trigger-point tenderness is the Doloriometer or Algorimeter. This device consists of a force meter attached to a circular probe that is pressed against the skin until pain is experienced.

If the reading of the force meter is 3.30 lb, and the diameter of the circular probe is 1.39 cm , what is the pressure applied to the skin? Give your answer in pascals.

Pressure is defined as force/area

You will need to change lb to Newtons
and cm to m.

1lb= 4.45N

one pascal is 1N per meter^2
