The a-36 steel guy wire ab (e=29,000 ksi) is unstretched when = 45o . if a load, which causes to become 48o is applied to the bar ac, determine: a. the normal strain in the wire. b. the normal stress in the wire. c. the force supported by the wire if the diameter of the wire is 2 in.

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

What are chlorofluorocarbons and what impact do they have on the atmosphere?

The slope of a velocity time graph over any interval of time gives the during that interval
