The circular section with a 3 m diameter is shown in Figure 1 below is subjected to a load of 2 0 0 kN at the eccentricities as shown. Determine the stresses at points a , b , c , and d which are located 3 0 degrees about the x - axis from each quadrant. The 2 0 0 KN point load is at coordinates ( 5 5 0 , - 4 0 0 )

Question 8 As shown in Figure Q 8 , a small trailer and its load have a total mass of 2 5 0 kg . The trailer is supported by two springs, each of constant \ ( 1 0 0 0 0 \ mathrm { ~N } / \ mathrm { m } \ ) , and is pulled over a road, the surface of which can be approximated by a sine curve with an amplitude of 4 0 mm and a wavelength of 5 m ( i .
Question 8 As shown in Figure Q 8 , a small

The weight of the wooden block shown in Fig. P 2 . 4 is 1 0 lb and the spring stiffness is 1 0 0 l b i n . A bullet weighing 0 . 5 lb is fired at a speed of 6 0 f t s e c into the block and becomes embedded in the block. Determine the resulting motion u ( r ) of the block. M o * * V o = ( M o + M ) * * V f u ( 0 ) = 0 d ( u ( 0 ) ) = V f ( i n i t
