Chapter 1, Problem 1.15P

The distance a spring stretches from its “free length” is a function of how much tension is applied to it. The following table gives the spring length y that was produced in a particular spring by the given applied force f. The spring’s free length is 4.7 in. Find a functional relation between f and x, the extension from the free length (y = y − 4.7).

Force  f   pounds ¯ 0 0.47 1.15 1.64 Spring length  y   inches ¯ 4.7 7.2 10.6 12.9

A physics lab consists of a large ball attached to a wire. Students hold on to one end of the wire, then whirl the ball around in circles and count the number of rotations per second. One group finds these numbers: ball mass= 320 gram, wire length= 1.3m, number of rotations/sec=2.5. The wire is made of steel with a diameter of 1mm and a Young's modulus of 20x10^10 N/m^2.How much does the wire stretch due to the tension on it? Should the students correct their data for the wire stretching?
‏A simply supported beam is subjected to two forces P and Q. Value of force P is 20 N and value of force Q is 40 N.If value of support force Ra is 30 N , then value of support force Rb is calculated as : O a . 70 N O b.30N O C60N O d . SON
A submarine is traveling at a depth of ‘95’ kilometers in the ocean, where the gagepressure is 840 Kg(f)/cm2 . The density and bulk modulus of elasticity of water at the top surface of the ocean are 1025 kg/m3 and 24000 kg(f)/cm2 respectively. Find the following:(i) What will be the density of water at the depth of 2.0 kilometers?(ii) What will be specific volume and change of volume at that depth?(iii) What is the pressure at the top surface of the submarine? How much will bechanged in pressure if submarine change direction from North to East?
