Question

solve      On a part-time job, you are asked to bring a cylindrical iron rod of density 7800kg/m3 , length 86.5cm and diameter 2.60cmfrom a storage room to a machinist. Calculate the weight of the rod, w. The acceleration due to gravity, g = 9.81m/s2 . Express your answer numerically in newtons. solve      On a part-time job, you are asked to bring a cylindrical iron rod of density 7800kg/m3 , length 86.5cm and diameter 2.60cmfrom a storage room to a machinist. Calculate the weight of the rod, w. The acceleration due to gravity, g = 9.81m/s2 . Express your answer numerically in newtons.

Explanation / Answer

area of rod = (pi) (.026/2)^2*.865
mass= area * density
.00045902090* 7800= 3.58036302 kg
weight = mass*gravity
23.58036302 kg* 9.8 m/s^2=
35.087557596 N
