Question

On a part-time job, you are asked to bring a cylindrical iron rod of density 7800 kg/m3 , length 94.0 cm and diameter 2.75 cm from a storage room to a machinist. Calculate the weight of the rod, w. Assume the free-fall acceleration is g

Answer 1

Step-by-step explanation:

Wt = ρVg

Wt = ρ(πD²/4)hg

Wt = 7800(π0.0275²/4)0.94(9.81)

Wt = 42.72152359...

Wt = 42.7 N
