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.

2. A strain gauge (see picture shown below from Omega) is a resistance element that is used to measure the fractional elongation experienced by a material. If it is attached to a beam that undergoes a deflection due to an impact, we can use the gauge to measure the deflection or monitor the frequency with which the beam vibrates. R1 SG1 wwwwww Lumin Assume we attach two strain gauges (SG1 and SG2) on opposite sides of the beam as shown above. If the beam deflects downward, SG1 elongates (so its resistance increases) while SG2 compresses (so its resistance decreases). Let's hook up the elements into a Wheatstone bridge as shown below. If R1=R2=100 92, and the nominal values of SG1 and SG2 when no strain is present are 100 as well, what is the value of Vout when the beam is deflected enough to cause SG1 to increase to 100.1 № and SG2 to decrease to 99.9 N? The voltage at the top of the bridge (10V in this case) is called the "excitation voltage". 10V Vout R2 Wall SG2 SG 1 SG 2 Beam
In exercise physiology studies, it is sometimes important to determine the location of a person's center of gravity. This can be done with the arrangement shown in the figure below. -2.00 m A light plank rests on two scales that read F 91 = 440 N and F 92 = 320 N. The scales are separated by a distance of 2.00 m. How far from the woman's feet is her center of gravity? m

3.) Consider the drawing below: Ť The 4.0-kg hinged rod is uniform and has a = 2.0m. The object at the end of the rod masses 8.0-kg. A wire affixed to the wall holds the rod horizontally. The wire makes an angle of 28° with the rod. a. Draw a picture. b. Draw a free-body diagram centered at the top of the loop. c. Use equilibrium considerations to determine the tension in the wire and the x and y forces on the rod's hinge.
