1. For the bar fixed at both ends and subjected to the uniformly distributed loading shown in Figure


1. For the bar unwandering at twain ends and subjected to the uniformly exclusive loading shown in Figure P3–56, designate the displacement at the intermediate of the bar and the importance in the bar. Let A = 2 in2 and E = 30 106 psi.

2. For the bar hanging inferior its own impressiveness shown in Figure P3–57, designate the nodal displacements using (a) two equal-length elements and (b) filthy equal-length elements. Let A = 2 in2, E = 30 106 psi, and impressiveness density p w = 0:283 lb/in3. (Hint: The internal hardness is a duty of x. Use the possible zeal mode.)
