On a part time job you are asked to bring a cylindrical iron rod of density 7800 kg/m^3, length 81.2 cm and diameter 2.75 cm from a storage room to a machinist. calculate the weight of the rod, w. the acceleration due to gravity, g= 9.81 m/s^2.

w= 36.9 n part a

part b) now that you know the weight of the rod, do you think that you will be able to carry the rod without a cart? yes or no?

3.76188 kg

36.9040428 N

Yes

Explanation:

g = Acceleration due to gravity = 9.81 m/s²

L = Length of rod = 81.2 cm

d = Diameter of rod = 2.75 cm

r = Radius =

A = Area of the cylinder =

v = Volume =

m = Mass

= Density of rod = 7800 kg/m³

Density

The mass of the rod is 3.76188 kg.

As the the mass of the rod is 3.76188 kg I will be able to carry the rod.

Weight

The weight of the rod is 36.9040428 N

see earlier

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
