    An unknown mass is hanging by a cable which is held by two ropes anchored to the roof at angles 60° and 40° that keep the mass at rest as shown in the figure. If the maximum tension either of the ropes can hold without breaking is 5000 N, determine the maximum value of the hanging mass that these ropes can safely support. You may consider the ropes and cable to be massless 60 40° An unknown mass is hanging...

  • Hanging weight

    Two ropes are connected to a steel cable that supports a hanging weight as shown in the figure.1) Draw a free-body diagram showing all of the forces acting at the knot that connects the two ropes to the steel cable.Draw the force vectors with their tails at the knot. The orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.2) Based...

    Consider a cylindrical cable with a hanging weight suspended from it. When the mass is removed, the length of the cable is found to be l0 = 4.53 m. After the mass is added, the length is remeasured and found to be l1 = 5.46 m. Determine Young's Modulus Y in N/m2 for the steel cable if the weight has a mass m = 85 kg and the cable has a radius r = 0.045 m. If we were to...

    A bucket of mass m is hanging from the free end of a rope whose other end is wrapped around a drum (radius R, mass M) that can rotate with negligible friction about a stationary horizontal axis. The drum is not a uniform cylinder and has unknown moment of inertia. When you release the bucket from rest, you find that it has a downward acceleration of magnitude (a). What is the tension in the cable between the drum and the...
