Exercise- -Load factor The picture shows the launch state of a missile sliding along the guide rail under the action of thrust P. It is known that the thrust P=450800N, the weight of the missile is G=20000N, the front leg A is a slider, the sliding friction coefficient is considered, and the rear leg B is a roller, ignoring the rolling friction. The launch angle is 0, try to use the above three expressions to calculate the load factor in the X and Y directions. R+RG cos B R₁₁ = Gl₂ ⋅ cos 0 |R₁f=F₁ e1 8.
