Why Strain Gauge Is Used In A Bridge Configuration?

Why Strain Gauge Is Used In A Bridge Configuration? Strain gauge resistance changes are typically measured in a bridge circuit, to allow for precise measurement of the small resistance changes, and to provide compensation for resistance variations due to temperature. Why are strain gauges used in bridge arrangement? For gauges on opposite legs, the bridge

Can Tension Negative?

Can Tension Negative? Can tension negative? Tension can either be positive or negative depending on where the coordinate axes are placed. Regardless of the upward direction being taken as positive or negative, the force balance equation for both gives the same result. What happens when tension is negative? A negative result merely means that tension
