1. Consider a simply supported beam AB as show in figure. a. If a concentrated load of 100kg can be placed only at any of the 1-meter interval points on the beam, Determine the values of the sample space of the reaction RA. 100 kg -10 @1 m- B RB RA b. The sample space of RA and RB; that all pairs of RA and RB such that RA +RB = 100 belong to the sample space. With a graph showing this sample space. 2. From historical data of floods for a river, suppose the annual maximum flood level above the mean river flow range from 1m to 5 m. a. If the annual maximum flow is measured in a increment of 0.1m, determine the sample space of the annual flood. b. If the event of annual flow exceeding 3.0 m, what is the sample space
