- A woman stands on the end of a 12 m long uniform beam that has a pivot 3 m from the end the woman is standing on. If the beam is balanced and the woman has a mass of 80 kg, then what must the mass of the beam be? A) 20 kg, b) 40 kg, c) 80 kg, d) 160 kg or e) it would be impossible for the beam to be balanced.When just a single force is present, can an item be in equilibrium? Explain.Q18
- When just a single force is present, can an item be in equilibrium? Explain.3. Consider the system shown. A 5.00 m beam supports a mass of 3000 kg attached to a cable. The mass of the beam is 1000 kg. Assume that the mass of the beam is uniformly distributed throughout its length. (a) Determine the tension in the cable (b) Calculate the horizontal and vertical components of the force exerted at point O. 5.00m 3000 kg 45.0°34. Please help answer this question thank you so much!:))
- Question 1: #51 A 3.0-m-long rigid beam with a mass of 100 kg is supported at each end, as shown in Figure below. An 80 kg student stands 2.0 m from support 1. How much upward force does each support exert on the beam?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). (Due to the nature of this problem, do not use rounded intermediate values in your calculations).A 6.0 m long ladder AB leans against a smooth wall making an angle of 60º with the floor (Figure 3). The ladder is uniform and has a mass of 20.0 kg.(a) Determine the forces exerted on the ladder by the floor and the wall (i.e. at A and B, respectively).(b) Determine the minimum value of the coefficient of static friction to prevent the ladder from slipping.
