FE CIVIL EXAM - Things to know
Force = - Answer✔mass * acceleration
Weight (SI system) = - Answer✔Mass * gravity
Mass is a - Answer✔Constant measurement and dimensionless quantity of the amount of
matter in a particle or object
Weight is - Answer✔A measurement that varies with gravitation field and is a force
The units for mass and weight (force) in SI are - Answer✔Kilograms & newtons
The units for mass and weight in the English system are - Answer✔Pounds-mass (lbm) &
pounds force (lbf)
The gravitation constant to convert lbf to lbm is - Answer✔gc= 32.2 lbm-ft/lbf-sec^2
Weight in lbf (English system)= - Answer✔(Mass (lbm) * gravity) / gravitation constant
The acceleration of gravity for earth is - Answer✔32.2 ft/sec^2 (English) and 9.81 m/s^2 (SI)
Force (SI system)= - Answer✔Mass * acceleration

Force in lbf (English system)= - Answer✔(Mass (lbm) * acceleration (ft/sec^2))/gravitational
constant
Unit weight = - Answer✔Weight/volume or (mass*gravity)/volume
The main difference between the English and metric system when it comes to force and mass -
Answer✔In english force and mass share a unit (lbf & lbm), metric does not
What is the Slope formula in terms of y & x - Answer✔(Y2-Y1)/(X1-X1)
The formula to get a slope of a perpendicular line is - Answer✔m1=-1/m2
Standard equation of a line - Answer✔y=mx+b, where m is the slope and b is the y-intercept
General form of an equation of a line - Answer✔Ax+By+C=0 aka mx-y+b
Point slope form of a line - Answer✔y-y1=m(x-x1)
The length of a vector (if origin is 0,0,0)= - Answer✔√(ax²+ay²+az²)
In matrices a determinant symbol is - Answer✔|A|
The magnitude of a vector is - Answer✔The length of a vector; magnitude is a scalar quantity
(size no direction)
