A toddler weighs 10 kg and raises herself onto tiptoe (on both feet). Her feet are 8 cm long with each ankle joint being located 4.5 cm from the point at which her feet contact the floor. While standing on tip toe: (a) what is the upward normal force exerted by the floor at the point at which one of the toddler’s feet contacts the floor? (b) what is the tension force in one of her Achilles tendons? (c) what is the downward force exerted on one of the toddler’s ankle joints?

V for vagsak. Two identical, uniform 1.50[m]- long beams weighing 150[N] each are connected at one end by a frictionless hinge. The beams are suspended from the ceiling by vertical wires such that they form a "V". A light horizontal crossbar is attached at the midpoints of the beams to maintain a specific angle between the beams. If the angle between the beams is 55.0°, what is the magnitude of the force exerted by the crossbar on each beam? Select one: O 156.2[N] 78.1[N] 214[N] 146.7[N]

A 5 kg beam 2 meters long is used to support a 10 kg sign by means of a cable attached to a building. The signs hangs from the end of the 2 m long beam, and the cable makes a 40 degree angle with the beam. What is the tension in the cable?

A scaffold of mass 71 kg and length 4.8 mis supported in a horizontal position by a vertical cable at each end. A window washer of mass 64 Kg stands at a point 2.4 m from one end. What is the tension in (a) the nearer (relative to the person) cable and (b) the farther (relative to the person) cable? (a) Number Units
