The rigid beam is supported by a pin at c and an a-36 steel guy wire ab. beam a b of length w with a uniform load distribution, pin-supported at c, with a cable from b to a above c at 30 degrees from horizontal. part apart complete if the wire has a diameter of 0.5 in., determine how much it stretches when a distributed load of 200 lb/ft acts on the beam. the material remains elastic.

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
