An object attached to a coiled spring is pulled down a distance 8 units from its rest position and then released. Assuming that the motion is simple harmonic with period T=5 seconds, write an equation that relates the displacement d of the object from its rest position after t seconds. Also assume that the direction of positive motion is up. d= cos (O (Simplify your answer. Type an exact answer, using z as needed. Use integers or fractions for any numbers in the expression.)

Crack AB of a slider crack mechanism shown in Figure 2 rotate at a constant speed of 300 rpm in clockwise direction. The connecting rod BC has a length of 1 m and incline at 45o to vertically positioned piston C. No angle or length for AB is given in the original question, thus I assume the angle is 70o because of the rough drawing I did here. Draw the displacement diagram of the mechanism shown in Figure 2 to scale. Use a vector diagram to determine the velocity of the piston C and connecting rod BC. Calculate the acceleration of piston C and the angular acceleration of connecting rod BC.

Question #7: A bead B slides down and around a cylindrical surface on a helical wire (see figure below). The vertical drop of the bead as angle theta changes by 2pi is called the pitchp of the helix. R is the radius of the helix. First, noting that theta (and therefore also z) is a function of time, write expressions for r, v, and a of the bead vs. the coordinate system origin. Next, for the values of R = 0.3 m, p = 0.2 m, and theta = 0.6t rad (time in seconds), find the vector expressions for both velocity and acceleration when t = 10 s.
