Que. | A 30m chain was found to be 20 cm too long after chaining 1500 m. The correct length of the total distance chained will be : |
Answer is given in question...The right answer is 1510m30-20=101500 10=1510m
ReplyL = Designated length of the chain = 30m L'= Incorrect length of the chain=30 0.2 = 30.2 ml'= measured length of a line = 1500m.l= correct lenght of todal distance l = l'*(L'/L)= 1500*(30. 2/30)= 1500 X 1·00= 1510mso,near about the wright answer is= 1505m
ReplyFor chainage 1500mAverage error 0.1mIncorrect lenght 30 0.1Ture length1500 *30.1÷30=1505m
