5. A 210-N mass is suspended from a horizontal beam by two cables that make angles of 29° and 53⁰ with the beam. Find, using vectors, the tension in the cables. A vector diagram is required.

An incline is tilted at an angle of 6.7° above the horizontal. A box of mass 34 kg is pushed up the incline with a force F along the incline. If the acceleration of the box is 1.1 m-s2, calculate the magnitude of F (in N) that is needed.

(a) Calculate the tension (in N) in a vertical strand of spiderweb if a spider of mass 8.00 x 10¯° kg hangs motionless on it. (Enter a number.) 0.000784 N (b) Calculate the tension (in N) in a horizontal strand of spiderweb if the same spider sits motionless in the middle of it much like the tightrope walker in the figure. 5.0° 5.0° T. TR w T. TR The strand sags at an angle of 15.0° below the horizontal. (Enter a number.) 0.046688914 X N Compare this with the tension in the vertical strand (find their ratio). (Enter a number.) (tension in horizontal strand) / (tension in vertical strand) =

An elevator is supported by a cable and moving downward through the elevator shaft at a constant speed. How does the upward tension force compare to the downward force of gravity? O The upward tension force is stronger than the downward force of gravity. The downward force of gravity is stronger than the upward tension force. The tension force and the force of gravity are of equal strength.
