Consider the two wood pieces that are connected by a velcro as indicated below. The block is subjected to a tension force P and has dimensions b 2 in and h = 4 in. The velcro can sustain the maximum normal stress Om-1 psi and the maximum shear stress Tn-7 psi. Use α = 20°. What is the maximum value of the force P that can be applied to the block before the velcro breaks connection?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
