- A meter stick is hanging from the ceiling at the 50 cm marker, perfectly in balance.. A 10 kg mass is tied to the meter stick at the 70 cm marker. A 10 kg mass is tied to the meter stick at the 80 cm marker. Where should a 20 kg mass be placed to maintain equilibrium? 25 cm 10 cm 20 cm 35 cmA cargo ship is loading using a boom crane, which is a 15 m long pole with a cable for lifting cargo which is suspended from the end of the pole. The boom is raised via a cable attached at a point that is 2/3 of the distance to the end of the pole. At one point the crane is lifting an 900 kg crate with the pole making a 30 degree angle with the horizontal, while the cable makes a 40 degree angle with the horizontal. Estimate the tension on the cable.What will happen when the supports are removed from this system? 20 kg 30 kg 2 1.75 1.5 1.25 0.75 0.5 0.25/ 0.25 0.5 0.75 1 1.25 1.5 1.75 2 Meters Meters A
- A 7-kg mass (m1) hangs from a cord that runs through a pulley and back down to attach to a 6-kg mass (m2) that is hanging from the other side. The pulley has a mass of 5.00-kg and a diameter of 20-cm. Find: A) the tension in the cord supporting m1 and the tension in the cord supporting m2; B) the tension in the cord supporting the pulley. C) Why is the answer to B) not equal to the sum of tensions in A)? Why is it not equal to the sum of the three weights?Given answer step by step with all detailsAt takeoff a commercial jet has a 45.0 m/s speed. Its tires have a diameter of 0.550 m.

Why is it not equal to the sum of the three weights?A 2.00 m long horizontal uniform beam of mass 20.0 kg is supported by a wire as shown in the figure. The wire makes an angle of 20.0 degrees with the beam. Attached to the beam 1.40 m from the wall is a ball with a mass of 40 kg. What is the tension in the string? a)1,000 Nb) 1,090 N c) 2,100 N d) 2,250 N e) 2,680 NAfter an unfortunate accident occurred at a local warehouse, you were contracted to determine the cause. A jib crane collapsed and injured a worker. An image of this type of crane is shown in the figure. The horizontal steel beam had a mass of 90.20 kg per meter of length, and the tension in the cable was T = 12820 N. The crane was rated for a maximum load of 500 kg. The acceleration due to gravity is g = 9.810 m/s². 2.250 m, 0.594 m, x = 1.250 m, and h = If d = 5.290 m, s = what was the magnitude of W₁ (the load on the crane) before the collapse? What was the magnitude of force Fp at the attachment point P? h W₁ = Fp = d 0 W₁ L 1 N N
