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?
