Considering only (110), (1 1 0), (101), and (10 1 ) as the possible slip planes, calculate the stress at which a BCC single crystal will yield if the critical resolved shear stress is 50 MPa and the load is applied in the [100] direction.

Annealing is a process by which steel is reheated and then cooled to make it less brittle. Consider the reheat stage for a 100-mm-thick steel plate ( 7830 kg/m3 , c 550 J/kg K, k 48 W/m K), which is initially at a uniform temperature of Ti 200 C and is to be heated to a minimum temperature of 550 C. Heating is effected in a gas-fired furnace, where products of combustion at T 800 C maintain a convection coefficient of h 250 W/m2 K on both surfaces of the plate. How long should the plate be left in the furnace

The substance called olivine may have any composition between Mg2SiO4 and Fe2SiO4, i.e. the Mg atoms can be replaced by Fe atoms in any proportion without altering the crystal structure except by expanding it slightly: this is an example of a binary solid solution series. For different compositions, the lines in the powder diffraction patterns are in slightly different positions, because of the cell expansion, but the overall pattern remains basically the same. The spacing of the lattice planes varies linearly with composition, and this can be used in a rapid and non- destructive method of analysis. a. The (062) reflection from olivine is strong and well resolved from other lines. Calculate d062 for an olivine that displays its (062) reflection at a Bragg angle of 37.21° (i.e., a diffraction angle of 74.42°) when x-rays with a wavelength of 0.1790 nm are used. b. The d062 spacing as measured accurately for synthetic materials is 0.14774 nm for Mg2SiO4 and 0.15153 nm for Fe2SiO4. What would be the approximate composition, expressed in mol.% Mg2SiO4, of an olivine material for which do62 has the value obtained in part 2.1 above?

A bathroom scale uses four internal strain gauges to measure the displacement of its diaphragm as a means for determining load. Four active gauges are used in a bridge circuit. The gauge factor is 2, and the gauge resistance is 120 Ω for each gauge. If an applied load to the diaphragm causes a tensile strain on R1 and R4 of 40 x 10-6, while gauges R2 and R3 experience a compressive strain of 40 x 10-6, estimate the bridge deflection voltage. The supply voltage is 5 V. a,b,c or d? a.400 x 10-6 V b.600x10-6V c.800x10-6V d.1000 x 10-6 V

B) 94 psig

C) 100 psig

D) 90 psig

The temperature and pressure of an ideal gas are **directly proportional**

The **pressure **of the system should be in the range **B) 94 psig**

The **given **refrigerator parameters are;

The **temperature **of the system and the surrounding, T₁ = 75 °F **= 237.0389 K**

The **pressure **to which the **system **was charged with nitrogen, P₁ **= 100 psig**

The **temperature **to which the system dropped, T₂ = 50 °F** = 283.15 K**

The **required **parameter;

The pressure, P₂, of the system at 50°F

**Method**:

The **relationship **between **pressure **and **temperature **is given by **Gay-Lussac's law** as follows;

At constant volume, the pressure of a given mass of gas is directly proportional to its temperature in Kelvin

Mathematically, we have;

**Plugging** in the values of the variables gives;

Therefore;

The closest option to the above pressure is option **B) 94 psig**

Learn more about **Gay-Lussac's** law here;

B 94 psig because the temperature dropped too

The law requires employers to provide their employees with working conditions that are free of known dangers. The OSH Act created the Occupational Safety and Health Administration (OSHA), which sets and enforces protective workplace safety and health standards.
