Landmark trilateration employing reference beacons is used to locate the (x, y) coordinates of a robot. The location of landmark number 1 (P1) is at the origin and the location of landmark number 2 (P2) is on the x axis at a positive distance x2 away from the first landmark (that is, P1 coordinates are (0, 0), and P2 coordinates are (x2, 0). The robot is at location (xR, yR), which will be determined based on the information provided below. Find the robot location (xR, yR) given the following: x2 = 25.3 m (where x2 represents the distance between the landmarks) d1 = 53.7 m (where d1 is the distance between the robot and landmark number 1) d2 = 48.2 m (where d2 is the distance between the robot and landmark number 2) Be sure to find the xR coordinate of the robot location and find both possible values of the yR coordinate of the robot location

Electrical transmission towers are stationed at 350 m intervals and a conducting cable 2cm in diameter is strung between them. How many wires should each tower carry toensure structural integrity during a tropical storm? The towers are designed to withstandup to 180 kN of transverse force and during a cyclone, wind can blow up to 200 km/h.Assume there is no interference between the wires and take air density as 1.2 kg/m3and viscosity as 1.7×10-5 Nsm-2 . If the smooth insulation on the wires is mechanicallyroughened up before application what effect it will have on the design? Also, establishwhether the wires are likely to be subjected to self-induced vibrations and if so what the frequency would be. The frequency of such forced vibration, sometimes called self-induced vibration, may be calculated from an empirical formula due to Vincent Strouhal: fd⁄Uo = 0.198(1 − 19.7⁄Re) 250 < Re < 105
