5. The force (in kN) required to stretch tendon 1, with cross-sectional area A = 1.0 x 107m? and unstretched length 1.5 cm by a distance (in mm) was measured and plotted. Tendon 1 broke at point P. A tendon 2 is made of the same tissue and has the same cross-sectional area. But tendon 2 has an unstretched length of 3.0 cm, twice that of tendon 1. About what force would be required to stretch this second tendon by 20 mm? Force (kN) Stretch (mm) 6. Review the demo from lecture: https://www.youtube.com/watch?v=HEI6XhgNWtg. What is the mass of the bar? What is the buoyant force when immersed? What is the volume of the bar? What is the density of the bar? All numbers you need should be in the video except the density of water, which is 1000 kg/m?. Be sure to give a complete explanation. The starting point is a free body diagram of the block. S
