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.

Question 26 of 31 > Attempt 1 Two steel wires are connected together, end to end, and attached to a wall. The two wires have the same length and elastic modulus, but the ratio of the radius of the first wire n to the radius of the second wire r is 9: 3. 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 3.150...
A 25.0 ? steel wire and a 50.0 ? copper wire are attached end to end and stretched to a tension of 145 ?. Both wires have a radius of 0.450 ??. and their densities are 7.86 ? 10? ??/?? for the steel and 8.92 ? 10? ??/?? for the copper. (Note that these are mass densities, mass per unit volume, NOT linear mass densities, mass per unit length.) How long does a wave take to travel from one end...
In the figure, a 140 kg uniform log hangs by two steel wires, A and B, both of radius 1.00 mm. Initially, wire A was 2.50 m long and 2.20 mm shorter than wire B. The log is now horizontal. Young's modulus for steel is 2.00 × 1011 N/m2. What are the magnitudes of the forces on it from (a) wire A and (b) wire B? (c) What is the ratio dA/dB?
As indicated in the figure, a steel ball (m 200 g) is attached to a massless elastic cord which is initially not stretched. When the ball is released from rest at A, t slides without friction through a thin curved tube with constant radius of curvature r = 70.0 cm. The cord stretches as the ball slides down the tube and follows the curvature of the surface, as indicated by the thick dashed line in the figure. Furthermore, the cord...
A 4-m long, 150-kg steel beam is attached to a wall with one end connected to a hinge that allows the beam to rotate up and down. The other end of the beam is held in a horizontal position with a cable that makes a 27° angle with the beam and is attached to the wall (see (Figure 1)). What is the tension force that keeps this beam in static equilibrium?
A 4-m long, 150-kg steel beam is attached to a wall with one end connected to a hinge that allows the beam to rotate up and down. The other end of the beam is held in a horizontal position with a cable that makes a 27° angle with the beam and is attached to the wall. A mass of 75 kg is hung from the beam 3 meters away from the hinge (see (Figure 2)). Now what is the tension force...

P6.042 The composite shaft shown in the figure consists of two steel pipes that are connected at flange B and securely attached to rigid walls at A and C. Steel pipe (1) has an outside diameter of 173 mm and a wall thickness of 6 mm. Steel pipe (2) has an outside diameter of 101 mm and a wall thickness of 7 mm. Both pipes are 3.4 m long and have a shear modulus of 80 GPa. If a concentrated...
Two parallel rods are each 0.39 m in length. They are attached at their centers to a spring that is initially neither stretched nor compressed. The spring has a spring constant of 220 N/m. When 1200 A of current is in each rod in the same direction, the spring is observed to be compressed by 2.7 cm. Treat the rods as long, straight wires and find the separation between them when the current is present. Number i Units The x,...
