This linear relationship describes how springs — and even ligaments under small deformation — resist displacement.
What is Hookes Law F=kx
The units of energy J can be broken down into these base SI units.
kgm^2/s^2
A thermodynamics problem uses the ideal gas law at extremely high pressure and low temperature.
What is the ideal gas assumption is invalid?
This type of force is generated by muscles, which can only pull and not push.
What is tension (tensile force)?
This famous scientist developed the theory of relativity, which influenced modern physics and engineering.
Who is Albert Einstein?
This equation focuses on how internal bending moments create stress that varies linearly across a beam’s cross-section.
What is flexural stress equation σ=I/My
If force is in newtons and velocity in m/s, multiplying them gives these units.
What is Watts (power)?
In a circuit, the output voltage is always zero because both measurement probes are connected to ground.
What is the voltage is measured between the same node (no potential difference)?
This type of joint allows movement primarily in one plane, like the knee or elbow.
What is a hinge joint?
This inventor is credited with improving the steam engine, helping drive the Industrial Revolution.
Who is James Watt?
This exponential equation describes how voltage decays over time in a capacitor, and appears in many biological and thermal systems.
RC discharge equation (V(t)=V0e−t/RC)
The units of Young’s modulus are the same as this physical quantity.
What is stress (Pa)?
A component operating at high temperature slowly deformed over time, even though the applied stress remained constant.
What is Creep?
An increase in blood velocity through a narrowed artery results in a decrease in this quantity, according to Bernoulli’s principle.
What is pressure?
I was a biomedical engineer who helped develop one of the first successful artificial hearts.
Who is Willem Kolff?
