The slope of this curve is designated as, k, and is called the spring constant. Thus F =k d → F = kd The spring constant k has units of Newtons per millimeter (N/mm). 8 Problem: A rigid bar of length, L, is supported at the ends by two springs, both having spring constant, k, as shown in Figure (a). Find the forces in and elongations of the springs due to the weight of the bar. Neglect the weight of the springs. k Undeformed position of the bar k dA dB A B L Figure (a) Solution: Draw a free body diagram.
All are at the same location. 3 Problem: A cylindrical bar has a portion hollowed out as shown in Figure (a). 72 E-06 kg/mm3 . Find its total weight and center of gravity. The y axis is aligned with the gravity vector. y 15 mm x 5 mm 50 mm 100 mm Figure (a) Solution: The total weight is the volume times the mass density times the acceleration due to gravity. From axial symmetry we know the center of gravity will lie on the centerline of the cylinder. We find the x location by summing moments about the z axis.
Each of the two force members is shown as a solid line. The actual geometry of the cross section of the member is not of concern at this time. Only the cross sectional area is relevant. The pinned joints are sometimes shown as small circles (Fig. 2a). Other times the pinned joints are implied and no circles are shown (Fig. 2b). 2 Pinned joints are free to translate in directions in which they are not restrained. 2 the lower left joint is restrained in both the x and y directions, and thus is fixed.
