Problem 63

Youre designing a vacation cabin at a ski resort. The cabin has a cathedral ceiling as shown in Fig. 12.37, and you estimate that each roof rafter needs to support up to 170 kg of snow and building materials. The horizontal tie beam near the roof peak can withstand a 7.5-kN force. You can neglect any horizontal force from the vertical walls, and treat contact forces as concentrated at the roof peak and the outside edge of the rafter/wall junctions. Will the tie beam hold? Will it be in tension or compression?

Notes for Week 2 Physics 1 Instantaneous Velocity: Examples: 1. A jet engine moves along an experimental track (which we call the x axis). We will treat the engine as if it were a particle. Its position as a function of time is given by the 2 2 equation x = At + B, where A = 2.10m/s and B = 2.80m. (a) Determine the average...
