A base line measured with a steel tape gives an approximate length of 1000m. compute the correct length of the base line at mean sea level when the pull at the
Standardization equal 15 kg. The applied pull is 23 kg. The cross-sectional area of tape is 0.0645 cm2 and E=2.11 x 186kg/cm2.Temperatures Tm and To are 35°C and 15°C respectively. The difference in level of the two ends Of base line is 2m. Radius of earth, R=6400 km. Elevation of base line above mean sea level = 1000m

Let p1; p2 and p3 denote, respectively, the planes de ned by a1x + b1y + c1z = 1 a2x + b2y + c2z = 2 a3x + b3y + c3z = 3: it is given that p1; p2 and p3 intersect exactly at one point when 1 = 2 = 3 = 1. If now 1 = 2; 2 = 3 and 3 = 4 then the planes (a) do not have any common point of intersection (b) intersect at a unique point (c) intersect along a straight line (d) intersect along a plane.
