Asteel cable is used to support an elevator cage at the bottom of a 2000-ft-deep mineshaft. a uniform normal strain of 290.0 in./in. is produced in the cable by the weight of the cage. at each point, the weight of the cable produces an additional normal strain that is proportional to the length of the cable below the point. assume d = 2000 ft and d = 300 ft. if the total normal strain in the cable at the cable drum (upper end of the cable) is 500 in./in., determine (a) the strain in the cable at a depth of 300 ft. (b) the total elongation of the cable.

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
