The pressure exerted by a phonograph needle on a record is surprisingly large. If the equivalent of 1.00 g is supported by a needle, the tip of which is a circle 0.200 mm in radius, what pressure is exerted on the record in N/m2 ?
Solution to 12PE
Step 1 of 3</p>
We need to calculate the pressure exerted by the tip of the phonograph needle on the record.
Mass of the needle,
Radius of the tip of the needle,
Step 2 of 3</p>
The pressure exerted by a perpendicular force acting on a cross-sectional area is,
Area of the tip of the needle,
Force acting on the vinyl record is the force due to gravity on the needle thus,
