- A string or rope will break apart if it is placed under too much tensile stress. Thicker ropes can withstand more tension without breaking because the thicker the rope, the greater the cross-sectional area and the smaller the stress. One type of steel has density 7870 kg/m³ and will break if the tensile stress exceeds 7.0 x 108 N/m². You want to make a guitar string from a mass of 4.5 g of this type of steel. In use, the guitar string must be able to withstand a tension of 900 N without breaking. Your job is the following. Express your answer in meters.

By how much will the volume of the sphere change? (Hint: Pay attention to units) AV cm3A horizontally oriented 2" x 4" pine stud is securely clamped at one end to an immovable object. A heavy weight hangs from the free end of the wood, causing it to bend. Which surface of the stud is under compression, and which surface is under tension? 80 F3 Both the top and bottom surfaces are under compression. Both the top and bottom surfaces are under tension. The top surface is under compression and the bottom surface is under tension. The top surface is under tension and the bottom surface is under compression. Neither the top nor the bottom surface are under tension or compression. Is there any place within the stud that is neither stretched nor compressed?

- 1 iron 40 cm steel 70 cm Henry has a rod that is made out of 2 parts. An iron and steel section. The iron section is 40cm long (Y₁=9.1 x 10¹⁰ N/m²). The iron piece is attached to a steel piece that is 70 cm long (Y,=7.0 x 10¹0⁰ N/m²). The rod has a uniform cross sectional diameter of 3.40 cm. Determine the total compression (in mm)when henry uses a compressive force on the rod of magnitude F=6000N.
