1. The big bird perches in the middle of a telephone wire. Its mass is 250 g. The wire makes an angle with respect to the horizontal. You can ignore the small birds for this problem. Draw a careful free body diagram for the big bird. b. Show that the tension in the line T is given by a. mg 2sine for the birds T = C. Find T if = 1° . d. Find T if 0 = 30°. e. Explain in words why a larger angle corresponds to a smaller tension in the wire.
