strain. In this application note, we will be more specific and define the term STRAIN to mean deformation per unit length or fractional change in length and give it the symbol, . See Figure 1. This is the strain that we typically measure with a bonded resistance strain gage. Strain may be either tensile (positive) or compressive (negative). See

Operating with very little actual movement, strain gauges tend to be stiff and insensitive to very small loads. The proof ring, on the other hand, is a comparatively floppy beam capable of moving more freely under load—only relatively speaking, because the distance moved needs to be less than the overall stroke e.g., ±0.5 mm of the linear

ε c r t, t 0 is a creep strain, ε k o p t is a total strain, ε s h t is shrinkage strain, ε e l t, t 0 is an elastic strain, σ is the compressive stress, E c r t, t 0 is the modulus of creep. The actual creep properties of the three tested mortars show when the stress influence is taken out from the strains.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Gauge pressure is the pressure relative to atmospheric pressure. Absolute pressure is the sum of gauge pressure and atmospheric pressure. Aneroid gauge measures pressure using a bellows-and-spring arrangement connected to the pointer of a calibrated scale. Open-tube manometers have U-shaped tubes and one end is always open.

A strain gauge is a sensor whose measured electrical resistance varies with changes in strain. Strain is the deformation or displacement of material that results from an applied stress. Stress is the force applied to a material, divided by the material’s cross-sectional area. Load cells are designed to focus stress through beam elements where
