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
Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Cable AC exerts on beam AB a force P directed along line AC. The force P must have a 250-lb vertical component. C Q 55° B Determine the magnitude of the force P. (You must provide an answer before moving on to the next part.) The magnitude of the force P is Elb.

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.
I Re You're carrying a 3.6-m-long, 24 kg pole to a construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 cm from its tip.

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
