If the staff intercept on a staff located at 100 m from the level for five division deviation of the bubble is 0.050 m and if the length of one division of the bubble is 2 mm, then the radius of curvature of the bubble is 0.050 m and if the length of one division of the bubble is 2 mm, then the radius of curvature of the bubble tube is

If the magnitude of the resultant of two forces F and 2F acting at a point O is 50 N, and the included angle between F and 2F is 90°, then what is the magnitude of F ?

Consider the following assumptions in the analysis of a plane truss 1. The individual members are straight. 2. The individual members are connected by frictionless hinges. 3. The loads and reactions act only at the joints. Of these assumptions :
