CHANGE 7 TO 15lbs Analytical solutions using force components. Check graphically. One end of a timber roof truss is supported on a brick wall but not securely fastened. The reaction of the brick wall can therefore be only vertical. Assuming that the maximum capacity of either the inclined or horizontal member is 7 kN, determine the maximum magnitudes of F 1 and F 2 so that their resultant is vertical through the brick wall.
Sample Class Problems-Force and Acceleration Prob#l: Two people are pushing a stalled car (the mass of the car is 1850kg). One person applies a force to the car, while the other applies a force of 395N. Both forces act in the same of 560N also acts on the car, but in a direction opposite force arises because of friction and the extent to which the pavement opposes Find the acceleration of the car. direction. A third force to that in...
(2.2 Coaching Activity Three-dimensional Force Systems 4 of 5 > II Review Four forces are shown: F1, F2, F3, and F4. (Figure 1) Classify the x, y, and z components of each vector as being less than zero. equal to zero, or greater than zero. Drag the appropriate items to their respective bins. Learning Goal: To use the conditions of equilibrium to solve for unknown forces in a three-dimensional force system. For particle equilibrium, the sum of all forces must...
