Answer to Question #255394 in Mechanical Engineering for Gani

Question

An Autonomous Landmine Sweeper is required to search and detect 8 landmines each of area 30 cm² placed in a circular surface area as shown in picture below. The circular test area is 165 cm diameter. While the Vehicle dimensions are 16 cm width and 22 cm length

Answer 1

Area of Circle $A_c =\frac{\pi}{4}165^2 =21382.46 cm^2$

Area of Vehicle $V_c =16\times22=352 cm^2$

Area cover by a vehicle on Circle $A = \frac{21382.46}{352}=60.74 cm^2$

detect 8 landmines each of area 30 cm²$N = \frac{60.74}{3.75}=$ , then 1 landmine each of area

$A_(one)=\frac{30}{8}=3.75 cm^2$

landmine detect by vehicle $N = \frac{60.74}{3.75}=16$ Qty
