1) A 20 ft long x 15 ft wide room has a floor live load of 100 psf and dead load of 85 psf. Determine the floor’s total load in kips. 2) A 40 ft wide x 125 ft tall x 20 ft deep structure is subjected to a uniformly distributed horizontal (lateral) load of 50 psf on the wall of its broad face. Determine the total load on the broad face of the wall in kips.

3) A 2,000 lb load is placed on top of a rectangular prism having an 8” x 8” horizontal top surface. Determine the stress in the prism.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

The magnets are probably damaged or there not strong enough to attached to the refrigerator

You would need to take a picture so i can see
