QUESTION 7 side of a train which is accelerating forward, a ball of weight W is hanging by a light wire at rest from the ceiling. The wire makes an angl e figure. Which one of the following conditions must be true about the tension T in the wire?

Weight of the box: 14N y-component: -2N x-component: 0  There is a box at rest on a table. What is the magnitude of normal force? What the maximum possible magnitude of the force of static friction?

OU President Harroz is hanging an OU banner outside of Boyd house. The banner is hanging from a bar of length L that is supported by a cable attached a distance L/2 above the end of the bar. There are two options, attach the cable to the end of the bar (blue cable) or at a point somewhere nearer the middle of the bar (red cable). Let Fend be the tension if a cable is attached to the end of the bar and Fmid be the tension if a cable is attached closer to the middle of the bar. (There is only one cable at a time.) Let the mass of the sign be 6.07 kg and the mass of the bar be 4.02 kg. Let the red cable be attached a distance 0.60 L from the right end of the bar. What is the ratio of the forces, Fmid/Fend? Give your answer to three significant digits to avoid being counted off due to rounding. As this is a ratio, there are no units. L ලා L/2

A steel cable with mass is lifting a girder. The girder is speeding up. Draw a free-body diagram for the steel cable.
