1. What is the normal stress in the bar if load or normal force 5 kN and 250 mm2 a)0.02 kPa b) 20 Pa c) 20 MPa d) 20 kPa e) 200 N/mm2 ) All of the above Support Reactions. Generally, for bodies subjected to coplanar force systems, the supports most commonly encountered a· The support prevents translation in a given direction, then a force must be developed on the member in that direction. b. If rotation is prevented, a couple moment must be exerted on the member. c. The roller support only prevents translation perpendicular or normal to the sur d The roller exerts a normal force on the member at its point of contact. e. The member can freely rotate about the roller, a couple moment cannot be developed face. on the member All of the above f.
