memory aid

Our memory aid include more than 160 formulas for :
. the calculation of surfaces and/or volumes of common shapes, triangle, trapezoid, circle, ellipse, parabola, parallelepiped and cylinder, cone and pyramid, truncated pyramid and cone, heap of sand, sphere, ellipsoid, spherical sector, spherical segment, spherical cap and torus
. the main trigonometric relations used in topography or for solving triangles from known data
. A large number of elements of strength of materials essential to the sizing of parts that constitute the structure of the buildings. More precisely, calculation of the moment of inertia and the module of resistance of simple sections, rectangle, triangle, U and I-shaped beam, cylinder and half-circle and study of straight beams submitted to uniformly distributed or concentrated loads, beam on simple supports, console, beam embedded at its two ends, beam embedded at one end resting on a support at the other end and continuous beams with equal spans with, for each studied case, reactions of supports, bending moments in spans or on supports and beam deflections.
