Note : This material is for review and I recommend you guys to solve it to prepare yourself for the course. This should not be considered the only

material to review for exams. You should also watch lecture videos and review course material posted by the professor. Also, don’t worry much

and stress for exams. If you have problem solving this, we can do it together. All the best for your exams :).

1.) Determine the reactions at the supports.

2.) Determine the force P needed to pull the 50-kg roller over the smooth step. Take θ=30° .

3.) The beam is subjected to the two concentrated loads. Assuming that the foundation exerts a linearly varying load distribution on its

bottom, determine the load intensities w1 and w2 for equilibrium if P = 500Ib and L = 12ft.

4.) The beam of negligible weight is supported horizontally by two springs. If the beam is horizontal and the springs are unstretched when

the load is removed, determine the angle of tilt of the beam when the load is applied.

5.) Determine the components of reaction at the ball and socket joint A and the tension in each cable necessary for equilibrium of the rod.

6.) The bent rod is supported at A,B and C by smooth journal bearings. Determine the magnitude of F2which will cause the reaction C y

at the bearing C to be equal to zero. The bearings are in proper alignment and exert only force reactions on the rod. Set

F1=300 Ib .
