- 4. A string attached to a wall makes an angle of 35° with the vertical and is connected to a knot. Another string from this knot is holding a mass m. A third string attached to the knot makes an angle of 28° with the horizontal and has a tension of 34.0N. What is the tension in the other two strings and what is the value of the mass? 7 T = 34,0N (90-28 +35) 34N Sivi(180-35) Sin (145) Sin (07) Sin (18) 28° 1205-30 mA copper wire 4.2 m long stretches .20 cm when a force of 410 N is applied. Determine the diameter of the circular wire. Young Modulus for copper is 11 x 10^10 N/m^21. During a circus act, one performer swings upside down hanging from a trapeze holding another, also upside-down, performer by the legs. If the upward force on the lower performer is three times their weight, how much do the bones (the femurs) in their upper legs stretch? You may assume each is equivalent to a uniform rod 35.0 cm long and 1.80 cm in radius. Her mass is 59.0 kg. The Young's modulus for bones is 1.6 x 10¹⁰ N/m². Think & Prepare 1. For this problem, assume that the leg bones are uniform rods. 2. What kind of stress does the legs of the trapeze artist experience? Tensile, compressive or shear stress? How will you fund the cross-sectional area of the bone? 3. What type of elastic modulus is appropriate for this problem? 4. If the total upward force on the artist is given, what is the force on each leg? Enter to 3 significant figures Amount by which the femurs stretch = 0.381 cm Reflect: Is this stretch large or small? Compare it to the length of the leg.

- 1. A uniform bar has a small ball hanging at a distance x. The bar is 2.00 m long and has mass 4.00 kg, while the ball has a 3.00 kg mass. The Tension in the string is 100 N 37.0 Ar a) Find the Position “x" on the Rod where the ball is hanging b) Find the Force exerted by the Hinge (Point A) on the Rod After experimenting the bar showed to have a non uniform density that varies as P(x)=C(1+0.1x²) in the interval 045. A bar AB, of length 0.6 m and weight 3 N is suspended horizontally by two strings at its ends A and B. Given that its centre of gravity is 0.4 m from A, then the tension in the string at A is A 0.2 N B 1.4 N C 0.8 N D 1.0 N
