A force of 5000n is applied outwardly to each end of a 5. 0-m long rod with a radius of 34. 0 cm and a young's modulus of 125 × 108 n/m2. The elongation of the rod is: phy101.
The elongation of the rod is [tex]5.51 \times 10^{-4}m[/tex]`
Young Modulus of a substanceThe young modulus of a substance is the ratio of stress to the strain of material.
[tex]Modulus = \frac{Stress}{Strain}\\ Modulus =\frac{Fl}{Ae}[/tex]
where:
F is the applied force = 5000Nl is the length of the rod = 5.0mA is the cross-sectional area = [tex]\pi r^2 = 0.34^2 * 3.14 =0.362984m^2[/tex]
Required
Extension of the rod "e"
Substitute the given parameters into the formula to have;
[tex]e=\frac{Fl}{A \gamma} \\e=\frac{5000 \times 5}{0.362984 \times 125,00,000}\\e=\frac{25000}{45,373,000}\\e= 5.51 \times 10^{-4}m[/tex]

A two-day moving truck rental from best rentals costs $60 and $0. 35 per mile driven. A two-day moving truck rental from easy movers costs $80 and $0. 25 per mile driven. Let m represent the number of miles driven. Which equation can be used to find the number of miles for which the rentals would cost the same amount? 60 + 0. 35 m = 80 + 0. 25 m 60 m + 0. 35 = 80 + 0. 25 m 60 + 0. 35 m = 80 m + 0. 25 m 60 m + 0. 35 = 80 m + 0. 25.
The equation that can be used to find the number of miles for which the rentals would cost the same amount is 60 + 0.35m = 80 + 0.25m.
The given parameters:
Cost from best rentals = $60 + $0.35 per mileCost from the easy movers = $80 + $0.25 per mileThe number of miles driven = mThe equation at which the cost for both rentals would be the same is formulated as follows;
$60 + ($0.35)m = $80 + ($0.25)m
60 + 0.35m = 80 + 0.25m
The number of miles is calculated as;
0.35m - 0.25m = 80 - 60
0.1m = 20
[tex]m = \frac{20}{0.1} \\\\m = 200 \ miles[/tex]
Thus, the equation that can be used to find the number of miles for which the rentals would cost the same amount is 60 + 0.35m = 80 + 0.25m.
