2.6 The sanding-drum mandrel shown in Fig. P2.6 is made for use with a hand drill. The mandrel is made from a rubber-like material that expands when the nut is tightened to secure the sanding sleeve placed over the outside surface. If the diameter D of the mandrel increases from 2.00 in. to 2.15 in. as the nut is tightened, determine (a) the average normal strain along a diameter of the mandrel. (b) the circumferential strain at the outside surface of the mandrel. Sanding sleeve Fig. P2.6 Mandrel

Problem #3 (5 points): A mechanical system is subjected to normal and shear forces that cause normal strain of 0.002 (mm/mm) and shear strain of 0.001 rad. If the normal stress is 250 MPa and the Poisson's ratio is 0.3, determine the shear stress.
Please I need an answer within half an hour
Q5: At a point in a strained material the stresses acting on planes at right angles to each other are o, 30, MN/m² tensile, together with associated shear stresses which assumed clockwise in effect on oy plane. If the maximum principal stress is limited to 1002 MN/m² tensile, and xy-60 MN/m², calculate: (a) the magnitude of the o, and oy; (b) the values of the maximum and minimum principal stresses; (c) the directions of the principal planes; (d) the maximum shear stress.
The error in a measurement due to strain when using a tape measure depends on the material that it is made of. For a tape with a cross section of 10 mm by 0.7 mm, calculate how much error is introduced in inches into the measurement at a 300 ft length if the tape is pulled with 80 N and if the tape is made of: a) mild steel (E = 30 x 10^6 psi), b) polycrystalline aluminum (E = 10 x 10^6 psi) c) fiberglass composite (E = 3.5 x 10^6 psi in the long direction)

A hole is to be punched out of a plate having a shearing strength of 94 ksi. The compressive stress in the punch is limited to 320 ksi. Compute the maximum thickness of plate from which a hole 5.2 in. in diameter can be punched. If the plate is 27 cm. thick, determine the diameter of the smallest hole that can be punched.
