A force of 10^5N is applied to an aluminum rod (E= 70×10^9Nm2)with a length of 2.0 m and a cross section of 4.0 cm2. By how much does it stretch? If we cut the rod in half tie the two parts in parallel next to each other, and apply the same amount of force, by how much will they stretch?

A diamond rod and a tungsten rod have the same length and diameter and are subjected to the same force. If the diamond rod stretches by 2.30 times 10^-6 m, by what amount will the tungsten rod stretch? Young's modulus for diamond = 1.22 times 10^12 N/m^2; for tungsten = 3.60 times 10^11 N/m^2. A spider of mass 7.0 times 10^-4 kg hangs from a 75.4-cm-long thread whose diameter is 2.0 times 10^-3 mm. Young's modulus of thread is 3....
The multi-material rod below has force P=3 kN applied to it
The multi-material rod below has force P=3 kN applied to it. The center portion is steel, with E=207 GPa and yield strength Sy=250 MPa. The outer shell is aluminum with E=69 GPa and yield strength Sy=276 MPa. The center portion has cross-sectional area of 7.07 mm2 while the outer shell has cross-sectional area of 5.50 mm2 . The load P is applied through rigid plates (not pictured) so that the force is shared between the two materials. Note: This scenario is used...

Problem #1 (35 pts.) A solid 5 cm by 5 cm square aluminum rod, with a 70 GPa modulus of elasticity, is stretched by an unknown axial load. The initial rod length is 1 m, and its final length (after applying the axial load) is 1.0005 m. Assume that a strain gauge (with a gauge factor of 2.2) is firmly affixed to the rod, its active axis aligned with the length of the rod. You may assume the strain gauge...

An ECM operation is to be used to cut a hole into a plate of aluminum that is 12 mm thick. The hole has a rectangular cross section, 10 mm by 30 mm. The ECM operation will be accomplished at a current = 1200 amps. The specific removal rate for aluminum = 3.44×10-2 mm3-Amp/sec. Determine (a) feed rate, and (b) time required to cut through the plate. In the casting of steel under certain mold conditions, the mold constant in...

An aluminum cable with cross-sectional area 1.50 times 10^-6 m^2 is suspended from the ceiling. A mass is suspended from the free end of the cable to keep the cable straight and at a certain length. If the temperature of the cable is reduced by 10 C degree, by how much should the suspended mass be increased so that the length of the cable remains the same? The coefficient of linear expansion for aluminum is alpha = 23 times 10^-6...
