Physics

At a construction site, a helicopter is lifting two steel beams,each with a mass of 290 kg. One steel beam is attached directly tothe helicopter by a cable. The second steel beam is not attached tothe helicopter directly, but it is instead hanging directly belowthe first steal beam and attached to the first beam by anothercable. Assume the cables have no mass.

(a) If the steel beams are at rest, what is the tension in eachcord?

(lower cable) _______ N

(upper cable) _______ N

(b) If the steel beams are pulled upward with an acceleration of1.70 m/s2 calculate the tension is each cable.

(lower cable) ______ N

(upper cable) _______ N
