here,
the length of wire , l = 5 m
weight , W = 8000 N
the elastic limit of alloy , Y = 4 * 10^8 N/m^2 = stress /strain
4 * 10^8 = (W /(pi * r^2)) /(dl /l)
4 * 10^8 = (8000 /(pi * r^2)) /(0.05 /5)
solving for r
r = 0.0252 m
the minimum radius of the wire is 0.0252 m

The elastic limit of an alloy is 4.0×108 N/m2. What is the minimum radius ?min of a 5.0 m long wire made from the alloy if a single strand is designed to support a commercial sign that has a weight of 8000 N and hangs from a fixed point? To stay within safety codes, the wire cannot stretch more than 5.0 cm.
The elastic limit of an alloy is 6.0 x 108 N/m² What is the minimum radius min of a 5.0 m long wire made from the alloy if a single strand is designed to support a commercial sign that has a weight of 8000 N and hangs from a fixed point? To stay within safety codes, the wire cannot stretch more than 5.0 cm. I'min = m
Attempt 1 The elastic limit of an alloy is 4.0 x 108 N/m? What is the minimum radius min of a 5.0 m long wire made from the alloy if a single strand is designed to support a commercial sign that has a weight of 8000 N and hangs from a fixed point? To stay within safety codes, the wire cannot stretch more than 5.0 cm. min = 0.0252 m Incorrect
The elastic limit of an alloy is 5.0×108 N/m2. What is the minimum radius ?min of a 5.0 m long wire made from the alloy if a single strand is designed to support a commercial sign that has a weight of 8000 N and hangs from a fixed point? To stay within safety codes, the wire cannot stretch more than 5.0 cm. Answer in m
The elastic limit of an alloy is 5.0 x 108 N/m². What is the minimum radius r min of a 5.0 m long wire made from the alloy if a single strand is designed to support a commercial sign that has a weight of 8000 N and hangs from a fixed point? To stay within safety codes, the wire cannot tretch more than 5.0 cm. I'min = 0.04513 m Incorrect
V = ? 2M An object of mass 3M, moving in the +x direction at speed vo, breaks into two pieces of mass M and 2M as shown in the figure. If 01 = 67.0° and 02 = 24.0°, determine the final velocities Vj and v2 of the resulting pieces in terms of vo. 3M 0, M = ?
