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.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
