Q3: A 200-pound object is to be hung from the end of a rigid 8ft horizontal pole of negligible weight, as shown in Figure below. The pole in attached to a wall by a pivot and is supported by an 8ft cable that is attached to the wall at higher point. The tension on this cable is given by the equatior (T). Write a program to determine the distance d in order to minimize tension on cable. The program should calculate the tension at 0.1ft intervals from d=1ft to 7ft and should locate the position of that produce the minimum tension Cable W.ic.lp T = dIp -d² l=8ft Ip=8ft w=200Ib

- A 4-m long, 150-kg steel beam is attached to a wall with one end connected to a hinge that allows the beam to rotate up and down. The other end of the beam is held in a horizontal position with a cable that makes a 27° angle with the beam and is attached to the wall (see (Figure 1)). a.What is the tension force that keeps this beam in static equilibrium? b. A mass of 75 kg is hung from the beam 3 meters away from the hinge (see (Figure 2)). Now what is the tension force that keeps this beam in static equilibrium? c.What is the vertical component of the force that the hinge exerts on the beam?The see-saw is balance.d What is the magnitude of the weight of the person hanging off the edge? 4m- 2m.
