WebJul 17, 2024 · 3.3 Roller support. A roller support resists linear motion in one axis only, i.e. it allows a reaction force to be developed in one axis only. The roller support shown in Fig 5 below would allow a connected structure to move freely in the horizontal direction but would restrain the structure from moving vertically. WebTherefore, the reaction at the roller support is 0.8woL or rounded to two decimal places, 0.96woL. Step-by-step explanation. To determine the reaction at the roller support, we can use the equation of static equilibrium: ΣFy = 0 where ΣFy represents the sum of forces in the vertical direction. Since the beam is in static equilibrium, the sum ...
