A 3-meter rod with a weight of 1000 N is suspended by two cables and has a large box(3500N in weight ) tied to the right-hand side hanging vertically. The center of mass of the rod is .5min from the leftmost edge. One cable is exactly on the leftmost end of the rod with a tension of4000 N at an angle of 30 degrees to the rod . The second cable is 1 m to the right of the center ofmass and has an unknown tension. What is the tension in the second cable and what angledoes it make with the rod? You must draw a diagram so I can understand your answer.

An acrobat is walking on a tightrope of length L = 20.2 m attached to supports A and B at a distance of 20.0 m from each other. The combined weight of the acrobat and his balancing pole is 800 N, and the friction between his shoes and the rope is large enough to prevent him from slipping. Neglecting the weight of the rope and any elastic deformation, calculate the deflection y and the tension in portions AC and BC of the rope for values of x from 1 m to 19.0 m using 3-m increments. From the data obtained, a0 plot y vs x b) plot both Tension in AC and Tension in BC Vs x. Using the plots, determine (c) the maximum deflection of the rope, (d) the maximum tension in the rope, (e) the smallest values of the tension in portions AC and BC of the rope. A B |C 20.0 m

To get up on the roof, a person (mass 62.0 kg) places a 6.80 m aluminum ladder (mass 11.0 kg) against the house on a concrete pad with the base of the ladder 2.00 m from the house. The top of the ladder rests against a plastic rain gutter, which we can assume to be frictionless. The center of mass of the ladder is 2.00 m from the base, as measured along the ladder. The person is standing on the ladder 3.00 m from the base, as measured along the ladder. Find the normal reaction and friction forces (in N) on the ladder at its base. (Enter the magnitudes.)   normal reaction force  friction force

The following figure represents a bicep curl maneuver where the center of mass (CoM) of a 23 kg dumbbell is 0.29 m from the elbow joint (pivot). The mass of the arm is 5 kg and acts 0.17 m from the elbow joint, and the biceps tendon acts at a distance of 0.01 m from the elbow joint.  What is the required magnitude of the resultant joint reaction force (JRF) at the elbow in newtons (N) for the scenario described above in a) where static equilibrium is achieved.
