Answer:
48.4293354946 N
Yes
Explanation:
d = Diameter of rod = 2.95 cm
h = Length of rod = 92.6 cm
[tex]\rho[/tex] = Density of rod = 7800 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
Volume of rod
[tex]V=\dfrac{1}{4}\pi d^2h\\\Rightarrow V=\dfrac{1}{4}\times \pi\times (2.95\times 10^{-2})^2\times 92.6\times 10^{-2}[/tex]
Mass is given by
[tex]m=\rho V\\\Rightarrow m=7800\times \dfrac{1}{4}\times \pi\times (2.95\times 10^{-2})^2\times 92.6\times 10^{-2}\\\Rightarrow m=4.93673144695\ kg[/tex]
Weight is given by
[tex]W=mg\\\Rightarrow W=4.93673144695\times 9.81\\\Rightarrow W=48.4293354946\ N[/tex]
The weight of the rod is 48.4293354946 N
The mass of the rod is 4.93673144695 kg which is light. So, I will be able to carry the rod without a cart.
