A beam with an overhang is loaded by a uniform load of 3 kN/m over its entire length. Moment of inertia Iz 5 3.36 3 106 mm4 and distances to top and bottom of the beam cross section are 20 mm and 66.4 mm, respectively. It is known that reactions at A and B are 4.5 kN and 13.5 kN, respectively. The maximum bending stress in the beam is approximately:



(A) 36 MPa

(B) 67 MPa

(C) 102 MPa

(D) 119 MPa


(D) 119 MPa

If the nation's yearly total energy use and also the yearly gross national product [GNP] are graphed, the two graphs rise at the same rate until the mid-1970s, but they diverge from each other after about 1973

This divergence of the graphs shows that A) energy use increases when the nation's goods and services increase. B) U.S. energy efficiency decreased after 1973, due to lower energy prices. C) energy efficiency has played a large role in providing goods and services since 1973. D) as the price of goods and services decreases, energy use increases. E) an increasing GNP causes energy use to also increase.
