A sandwich board advertising sign is constructed as shown in the figure below. Hinge 2011 Brooks/Cole Thomson Learning Chain CG 80 0.50 m CG 1.30m Uniform board (CG at center) 1.10 m The sign's mass is 6.10 kg. (a) Calculate the tension in newtons in the chain assuming no friction between the legs and the sidewalk. N (b) What force is exerted in newtons by each side on the hinge? N

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

Two forces are acting on an object. Which of the following statements are correct?   a. The object is in equilibrium if the forces are equal in magnitude and opposite in direction. b. The object is in equilibrium if the net torque on the object is zero. c. The object is in equilibrium if the forces act at the same point on the object. d. The object is in equilibrium if the net force and the net torque on the object are both zero. e. The object cannot be in equilibrium because more than one force acts on it.
