- An elastic string is fixed at one end and is wound on a drum of diameter 0.2m so that the tension in the string increases as the angle through which the drum turns increases. The torque Ton the drum then varies according to the law: T = Sr20 where S = stiffness of elastic string (S=120KN/m) r = radius of drum As the drum starts at 0 = 0, the work done can be calculated using calculus, for any given value of 0, as shown: ST de Determine the work done by the drum if it rotates through an angle of 0 = 2/3,The below shown graph is drawn from the tabulated values of steel which we measured during the experiment of thermal conductivity: (Consider the value of heater power (Q') and the area of cross section (A) of the material from the tabulated values) x-axis 1 unit = 1 cm y-axis 1 unit = 10°C 80- 70- 60- 50- 40- 30- 20- 10- Distance X in cm 3 4 6. 8. 10 Calculate the following: Thermal conductivity of steel Value Calculated quantities Temperature T degree CelsiusJes 1:01 i docs.google.com/forms what is the Physicists recognize four fundamental forces.* Flectrical force O - Gravitational force -Strong nuclear force Weak nuclear force O -Muscular force Force of friction Ff is described by • Ff = µN * O p synovlal fluld in the Joints P -coefficient of fraction between two surface in The temperature of the human body is normally about 98.6°F.calculate the temperature of the body "C* oC = (5/9)x(oF-32) =5/9(98.6- 32)-37 oc oc=(9/5)x(of -32) =9/5(98,6-32) =13,3 Under resting conditions the body energy is being used as follows * O 27% by the liver and splee O 20-%by the skeletal musules Under resting conditions the body energy is being used as follows.
