The answer is D, but how??? Can you show me how? A traffic light is hanging...
A) A traffic light is hanging from two cables. Cable #1 pulls up and left, making an angle of 25o with the horizontal on the left, and cable #2 pulls up and to the right with a force of 180 N, making an angle of 45o with the horizontal on the right. Find the mass of the traffic light. B) At the park, a 4 m long seesaw is supported in the middle.A 35 kg child sits at the far...
#4 please A uniform sheet of metal in the shape of a hemisphere of radius 1 m is used as a sign. The hemisphere has a mass of 200 kg and is suspended by two vertical wires attached to points along its horizontal diameter. One wire is attached to the left end of the diameter and the other is attached to a point three-quarters of the way to the other end. What is the tension in each wire? A ladder...
Can someone please help me with this question? Write clearly and please explain why/how you use all of the recuired equations. (I just started studying physics, so please explain your steps) A point-shaped weight with the mass m = 2 kg is attached to a light thread with the length L = 3 m. The thread is attached to a solid plane according to Figure 1. The weight is initially raised, with the thread tightened to the angle α =...
PRACTICE IT Use the worked example above to help you solve this problem. A traffic light weighing 1.08 x 102 N hangs from a vertical cable tied to two other cables that are fastened to a support, as shown in Figure (a). The upper cables make angles of θ1-35.5° and θ2 54.5° with the horizontal. Find the tension in each of the three cables T3 108 N EXERCISE HINTS: GETTING STARTED I rMSTUCK!

Please can you tell me if my diagram is correct and how i did it is correct Is this correct that I can use 31 for my angle because it an opposite angle to the angle given in the picture (a) Find the tension in each cable supporting the 540-N cat burglar. (Assume the angle θ of the inclined cable is 31.00.) inclined cable horizontal cable vertical cable T, sin 31° -540 T,(0.5150) T2(0.5150) T, cos 31°-T, = 0 T,...
Can you describe how to get the answer A picture is hanging from the two ropes shown in the sketch. Find the tension in both ropes.
