27) I caught me a big shark, one having a mass of 650 kg. It is held up by a strong pole(solid black in the figure) that makes an angle of 55.0° with the horizontal and an attachedcable (light brown in the figure) at its end. The pole is uniform in construction, 4.00 m long,and has a mass of 50.0 kg. The cable makes an angle of 35.0° with the horizontal. Determinethe tension in the cable, and the x and y components of the force exerted at the base of thepole. Start off by drawing the Tension T on the cable and the x and y- forces at the base ofthe pole.35°55°

In Example 14.3, we found that one of the steel cables supporting an airplane at the Udvar-Hazy Center was under a tension of 9.30 103 N. Assume the cable has a diameter of 2.30 era and an initial length of 8.00 m before the plane is suspended on the cable. How much longer is the cable when the plane is suspended on it?

A beam held by a hinge, take 2. The left end of a beam of mass 17.9 kg is fixed to a wall by a hinge. The beam is inclined at 19.8 degrees from the horizontal; it is supported at its right end by a rope forming an angle of 30.3 kg with the horizontal.create a model for the orientation of the hinge force, relative to the x+ axis.
8₁ 02 9. The diagram of the leg shows the femur (1) and tibia (2). The quadriceps muscle (3) applies a force to the lower leg via a tendon (4) that is embedded with the kneecap (5). If the force applied by the muscle to the tendon is F 570 N, what is the force of the femur on the kneecap, if the leg is in equilibrium? A simplified model of the leg is shown next to the diagram. The leg bones are represented by two beams attached by a pin. The tendon is modelled by a rope and the kneecap acts like a pulley. The tendon above the kneecap makes an angle 8, = 38° with respect to the vertical, and the portion of the tendon below the kneecap makes an angle of 6₂ = 10° with respect to the vertical. Enter the x component, followed by the y component. Answer 1 of 2: Answer 2 of 2: Submit All Answers
A hungry 728-N bear walks out on a beam in an attempt to retrieve some ``goodies'' hanging at the end (see figure). The beam is uniform, weighs 216 N, and is 5.41 m long; the goodies weigh 82 N. When the bear is at ?=1.00x=1.00 m, find (b) the tension on the wire and (c) the magnitude of the beam's force on the wall. (This will be equal and opposite to the wall's force on the beam. Both ?x- and ?y-components will contribute.) what is Tension on the wire the Beam's force on wall. If the wire can withstand a maximum tension of 900 N, what is the maximum distance the bear can walk before the wire breaks?
a. Draw an extended FBD for the beam. b. Choose a point of rotation and write Newton's 2nd Law for rotation about that point of rotation. c. Solve for the magnitude of the tension in the wire attached to the beam. d. Solve for the force from the pin on the beam.
A spade is modelled as a uniform rod, of mass 2kg and length 90cm, attached to a uniform square lamina, of side 20cm and mass 0.5kg.

1) A 3 m long light (massless) board is supported at each end by cables. A painter weighing 900N stands 1m from the left cable. Calculate the tension in each cable.2)A 10m beam of mass of 300 kg extends over a ledge. The beam is not held down but simply rest on the surface. A 60 kg student has positioned the beam so that he can walk to the end of it. How far far the edge of the ledge can the beam extend?3) A ladder whose length is 10 m and whose mass is 40 kg rests against a frictionless vertical wall. Its upper end is a distance of 7.7m above the ground. The center of mass of the ladder is 1/3 of the way up the ladder. The coefficient of static friction between the ladder and the ground is 0.53. If a carpenter climbs 85% of the way up the ladder before it starts to slip, find the mass of the carpenter.4) A springboard diver of weight 582N stands at one end of a uniform 4.48 m diving board of weight 142N. The board is attached to two pedestals, one at the other end of the board…
