Astructural steel has an allowable stress of 21,600 psi. express this in pascal and mpa.

To solve this problem we will apply the conversion concepts given for the available units. Recall that the unit 'psi' is the expression equivalent to pounds per square inch applied on a surface. The force pounds in Newtons (mass per acceleration) are equivalent to

While square inches to square meters are equivalent to

Making the conversion for the elimination of the units we would have

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
