A sign is hung from a 16.8 kg horizontal boom. The boom is held in place by a cord that extends from above the wall, meeting the end of the boom at an angle of 26.1 degrees. If the sign is 18.8 kg and is hung from a point 3/4 of the length from the wall, what is the tension in the cord?

A sculptor has hung up a 45.0 kg horizontal rod of length 4.85 m . One end of the rod is supported by a pivot, and the other end is held up by a wire. The wire makse a 30.0 ∘ angle with the rod. If tension greater than 1450 N would snap the wire, what is the maximum distance from the pivot that a 68.0 kg person can sit on the rod? r=________m

A horizontal wire is hung from the ceiling of a room by two massless strings. The wire has a length of 0.22 m and a mass of 0.009 kg. A uniform magnetic field of magnitude 0.075 T is directed from the ceiling to the floor. When a current of I = 31 A exists in the wire, the wire swings upward and, at equilibrium, makes an angle φ with respect to the vertical, as the drawing shows. Find (a) the...

Suppose you’re building a contraption which contains a solid rod of length L = 12.9 m and mass 4.4 kg. This rod has its lower end barely above the ground at an angle of 36 degrees with respect to the horizontal, and is ultimately held up by a rope connected at a distance L/4 from the top of the rod making an angle of 24.6 degrees with respect to the rod. The top of the rod may rotate as it...
