Q. 29: A wire of length (L) and radius (r) is loaded with a weight (Mg). If (Y) and (o) denote the Young's modulus and Poisson's ratio of the material of the wire respectively, then the change in the radius of the wire is given by: Otr Ar = Mgr Mgr (b) Ar = To Y (a) Mgo Ar = MgY (d) Ar = (c) TT ry Tro

V A solid brass (bulk modulus 6.7 x 1010 N/m²) sphere is subjected to a pressure of 1.0 x 105 Pa due to the earth's atmosphere. On Venus the pressure due to the atmosphere is 9.0 x 106 Pa. By what fraction Ar/ro (including the algebraic sign) does the radius of the sphere change when it is exposed to the Venusian atmosphere? Assume that the change in radius is very small relative to the initial radius. Number i Units

A sphere of copper has a radius of 8.00 cm and is compressed uniformly by a force of 5.00 × 108 N. The bulk modulus for copper is 140 x 10⁹ N/m². Calculate the sphere's change in volume AV after compression. Calculate the sphere's final radius R. AV = R = 3.81 x107 Incorrect 0.075 -7 Incorrect m³ m

For a bronze alloy, the stress at which plastic deformation begins is 295 MPa and the modulus of elasticity (E) is 108 GPa. (a) What is the maximum load (Fy) that can be applied to a specimen having a cross-sectional area of 317 mm² without plastic deformation? (b) If the original specimen length is 121 mm, what is the maximum length to which it may be stretched without causing plastic deformation?
