26. Answer
Given ratio of radii =
Total extension, --------------(1)
-----------(2)
as we know or,
or, -------------------(3)
solving equations (1) and (3),we get
and
By equation(2)

Question 26 of 31 > Attempt 1 Two steel wires are connected together, end to end,...
Two steel wires are connected together, end to end, and attached to a wall as shown below. The two wires have the same length and elastic modulus, but the ratio of the radius of the first wire to the radius of the second wire is 5 : 2. As the wires are initially the same length, the midpoint of the combination coincides with the connection point. An applied force then stretches the combination by 2.650 mm while the two wires...
Can someone help me with this physics problem? Two steel wires are connected together, end to end, and attached to a wall as shown below. The two wires have the same length and elastic modulus, but the ratio of the radius of the first wire to the radius of the second wire is 9:2. As the wi with the connection point. An applied force then stretches t wires stay connected together. After the wires are the connection point? res are...
A person drops a cylindrical steel bar (Y = 5.00 × 1010 Pa) from a height of 3.10 m (distance between the floor and the bottom of the vertically oriented bar). The bar, of length L = 0.580 m, radius R = 0.00700 m, and mass m = 1.300 kg, hits the floor and bounces up, maintaining its vertical orientation. Assuming the collision with the floor is elastic, and that no rotation occurs, what is the maximum compression of the...
A person drops a cylindrical steel bar ( Y = 1.700 × 10 11 Pa ) from a height of 3.70 m (distance between the floor and the bottom of the vertically oriented bar). The bar, of length L = 0.950 m , radius R = 0.00650 m , and mass m = 2.000 kg , hits the floor and bounces up, maintaining its vertical orientation. Assuming the collision with the floor is elastic, and that no rotation occurs, what...
A person drops a cylindrical steel bar (Y = 1.000 times 10^11 Pa) from a height of 1.50 m (distance between the floor and the bottom of the vertically oriented bar). The bar, of length L = 0.720 m, radius R = 0.00650 m, and mass m = 0.600 kg, hits the floor and bounces up, maintaining its vertical orientation.

A person drops a cylindrical steel bar (Y= 1.10 x 1011) from a height of 3.50m (distance between the floor and the bottom of the vertically oriented bar). The bar, of length 0.86 m, radius 0.55 cm, and mass 1.70 kg, hits the floor and bounces up, maintaining its vertical orientation. Assuming the collision with the floor is elastic, and that no rotation occurs, what is the maximum compression of the bar? (answer in mm)
Figure < 1 of 1 Consider, for instance, a bar of initial length L and cross-sectional area A stressed by a force of magnitude F. As a result, the bar stretches by AL (Figure 1) Let us define two new terms: • Tensile stress is the ratio of the stretching force to the cross-sectional area: stress = 5 • Tensile strain is the ratio of the elongation of the rod to the initial length of the bar strain= 41 It...
