(a) A student stands a distance d = 0.450 m from the left end of a beam as shown in the figure. The beam is supported by three lines. Find the tension in each line (in N). Assume the beam is uniform, with length L = 2.00 m and mass 34.5 kg, and the weight of the student is 710 N. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) = = ܫܐܐ d+ Ť₂ -2.00 m N N m N T₁ 40.0⁰ (b) What If? The student now begins to walk to the right. If each of the lines can support a maximum tension of 750 N, which line fails first? O line 1 O line 2 O line 3 At what location does this occur (measured in m from the left end of the beam)?

A hungry bear weighing 730 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see the figure below). The beam is uniform, weighs 200 5.00 m long, and it is supported by a wire at an angle of 0 = 60.0°. The basket weighs 80.0 N. Goodies Q (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.) Choose File No file chosen This answer has not been graded yet. (b) When the bear is at x = 1.16 m, find the tension in the wire supporting the beam. N When the bear is at x = 1.16 m, find the components of the force exerted by the wall on the left end of the beam. (Assume the positive +x direction is to the right and the positiv direction is upward. Include the sign of the value in your answer.) Fx N N (c) If the wire can withstand a maximum tension of 775 N, what is the maximum distance the bear can walk before the wire breaks? m

A 40.0kg uniform platform is suspended by two cables, 2.00m apart, where the centre of the platform lies midway between the cables. A 5.00kg paint bucket is placed on the platform, 24.0cm to the right of the right cable. Determine the tension in each cable.

A uniform 37.0 kg scaffold of length 6.2 m is supported by two light cables, as shown below. An 82.0 kg painter stands 1.0 m from the left end of the scaffold, and his painting equipment is 1.6 mfrom the right end. If the tension in the left cable is twice that in the right cable, find the tensions in the cables (in N) and the mass of the equipment (in kg).
