2. A wire 4 meters long is stretched horizontally between points 4 meters apart. The wire is 25 mm2

in cross-section with a modulus of elasticity of 200,000 MPa. A load W placed at the center of the wire

produces a sag Δ.

2.a. Find the tension in the wire if sag Δ is 30 mm.

2.b What is the magnitude of the load W if sag Δ is 54.3mm
