Select Answer
Formula used and units
${\displaystyle E={\frac {\sigma }{\varepsilon }}},$ where
- $ E $ is Young's modulus
- $ \sigma $ is the uniaxial stress, or uniaxial force per unit surface
- $ \varepsilon $ is the strain, or proportional deformation (change in length divided by original length); it is dimensionless.
Both $ E $ and $ \sigma $ have units of pressure, while $\varepsilon $ is dimensionless. Young's moduli are typically so large that they are expressed not in pascals but in megapascals (MPa or N/mm2) or gigapascals (GPa or kN/mm2).
- 2kg
- 3kg
- 4kg
- 29.4kg
Select Answer
Weight = Mass × acceleration due to gravity.
29.4 = Mass × 9.8 m/s2
Mass = $ {29.4 N \over 9.8 m/s ^2 }= 3kg $
