You set up a Halloween prank by attaching a small board to a hinge above your front door. The far end of the board is held up by a cable that can be released by remote control. You place a spooky spider on the board that is dropped on unsuspecting trick-or-treaters when you release the cable. The drawing below shows the set-up. cable 40° Hinge 60 ст You use a board that is 60 cm long and the cable makes an angle of 40 degrees with the board when the board is held horizontally. You place the spider a distance of r = 37 cm from the hinge. The board has a mass of 2.2 kg and the spider has a mass of 1.6 kg. The hinge applies both a horizontal force and a vertical force. You will be asked to determine the direction of both of these forces (left, right, up, down). What is the magnitude of the tension in the cable in Newtons? T = What is the magnitude and direction of the horizontal force from the hinge? Enter a positive number for the magnitude. Fh = Direction ---Select--- What is the…
a D1 Sign Dz A 2.20kg pole is attached to a wall with a hinge as shown. A 5.70kg sign is suspended at the other end of a pole, where D, = 3.30m. A cable attached to the wall forms an angle a = 18.0° with the wall, and is attached to the pole a distance D, = 1.40m from the hinge. Assume the origin is at the hinge. What is the torque on

8. A uniform beam, length = 12 m, wt = 800 N, is hinged at the wall and makes an angle of 30° to the horizontal. A wire connected to the beam 2 meters from its end makes an angle of 45° to the beam. a) What is the tension in the wire? b) What is the vertical component of the force of the hinge and c) What is the horizontal component of the force of the hinge? 45 30
5) Consider a rigid steel beam of length L = 14.5 m and mass mb = 375 kg resting on two supports, one at each end. A worker of mass mw = 76 kg sits on the beam at a distance x from support A. Refer to the figure, though note that it is not drawn to scale. a) Enter an expression for the force support B must exert on the beam in order for it to remain at rest, in terms of defined quantities, x, and g. b) When the worker sits at a distance x = 7.5 m from support A, calculate the force, in newtons, that support B must exert on the beam in order for it to remain at rest. Use g with three significant figures. c) The force exerted on the beam by support A is measured and found to be FA = 2390 N. At what distance x, in meters, from support A is the worker sitting now?
