NAME: Assume that box B starts from rest at a distance r = 0.5m from pin A. At time t = 0, the arm is at an angle of 0= 0°, and then starts moving at a constant angular acceleration of ë = 2d. Note that the motion occurs in the vertical plane and that the coefficient of static friction between the box and arm is Hs = 0.5. Calculate and plot the angle at which the box begins to slip. You must show all diagrams such as the Free Body Diagram/s and Kinetic Diagram/s. Hint: You might want to start with the kinematics and express 0 and as a function of time. Solving the equations of motion might require you to solve a nonlinear equation (in time) which you can try do by plotting the resulting equation as a function of time and finding at what time the function becomes zero. r B A

If the roll rests against a wall where its coefficient of friction is -0.22 and you apply a force of 0.7 N at an angle of 40* from the vertical. Force F is also tangent to the roll. Determine the angular acceleration of the precious toilet paper. Mark a counterclockwise acceleration as positive and a clockwise acceleration as negative. Hint: Watch your vector direction for a above F Assume the roll can be treated as a cylinder with a mass of 0.21 kg, a width of 11.5 cm, and a radius of 7.5 cm. Point B is a vertical distance d=13 cm from point A. UBC Engineering

A box with mass m = 2.75 kg rests on the top of a table. The coefficient of static friction between the box and the table is μs = 0.71 and the coefficient of kinetic friction is μk = 0.34. Write an expression for Fm the minimum force required to produce movement of the box on the top of the table. Solve numerically for the magnitude of the force Fm in Newtons. Write an expression for a, the box's acceleration, after it begins moving. (Assume the minimum force, Fm, continues to be applied.) Solve numerically for the acceleration, a in m/s2.
