Axial loads are applied with rigid bearing plates to the solid cylindrical rods. One load of P = 90 kN is applied to the assembly at A, two loads Q = 50 kN are applied at B, and two loads R = 140 kN are applied at C. Determine the total change in length of the assembly.L1 = 0.26 m, E1 = 192 GPa, A1 = 0.0012 m2L2 = 0.40 m, E2 = 212 GPa, A2 = 0.0004 m2L3 = 0.34 m, E3 = 104 GPa, A3 = 0.0016 m2

Read DetailsThe Supplies account had a balance at the beginning of year 3 of $9,800. Payments for purchases of supplies during year 3 amounted to $51,700 and were properly recorded as supplies. A physical count at the end of year 3 revealed supplies costing $14,300 were remaining on hand. The required adjusting entry at the end of year 3 will include a debit to:

Read DetailsA 4.78 MeV alpha particle from a 226Ra decay makes a head-on collision with a uranium nucleus. A uranium nucleus has 92 protons. What is the distance (in femtometers, i.e. 1e-15m) of closest approach of the alpha particle to the center of the nucleus? Assume that the uranium nucleus remains at rest and that the distance of closest approach is much greater than the radius of the uranium nucleus.
