Use these interactive engineering tools to practice calculations, check your work, and better understand common engineering equations.
Choose one of the tools above to open its calculator. Only one tool will be displayed at a time.
Convert between common engineering length units.
Resolve a force into its horizontal and vertical components. The angle is measured from the positive horizontal x-axis.
Combine two forces using their horizontal and vertical components to find the magnitude and direction of the resultant force.
Solve common one-dimensional constant-acceleration kinematics problems. Choose the quantity you want to calculate and enter the known values.
Use Newton's Second Law to calculate force, mass, or acceleration using the relationship F = ma.
Calculate normal stress, strain, or elastic modulus using common Strength of Materials equations.
Calculate factor of safety, allowable stress, or failure strength using a basic strength relationship.
Calculate heat energy, mass, specific heat capacity, or temperature change using Q = mcΔT.
