Determine the component of the force along line AB. PAB= N use 2 decimal places 3. Find the angle between the force applied and its component along line AB. use 3 decimal places

Please answer the following question A cigarettes dispenser requires a south African five-rand (R5) coin with a mass of 9.5 g to dispense one cigarette with a mass of 0.2 g. The design of such a cigarette dispenser is based on a helical spring, of negligible mass, which is found to extend 0.1 mm under a mass of 0.2 g. The spring can support a total mass of a coin. As the customer place money on the dispenser, the spring and coin system displace vertically through 4 mm and release. 1.1. Provide a schematic representation of the mass and spring system. 1.2. Calculate the frequency of natural vibration of the dispenser. 1.3. Determine the velocity of the coin when it is 2 mm below its resting position.

Please show graphical method representation for all questions a b and c. please.... Thank you     A shaft turning at a uniform speed carries two uniform discs A and B of masses 10kg and 8kg respectively.  The centres of the mass of the discs are each 2.5mm from the axis of rotation.  The radii to the centres of mass are at right angles.  The shaft is carried in bearings C and D between A and B such that AC = 0.3m, AD = 0.9m and AB = 1.2m. It is required to make dynamic loading on the bearings equal and a minimum for any given shaft speed by adding a mass at a radius 25mm in a plane E.                                                                                          Determine:                       The magnitude of the mass in plane E and its angular position relative to the mass in plane A The distance of the plane E from plane A The dynamic loading on each bearing when the mass in plane E has been attached and the shaft rotates at 200 rev/min. For the bearing loads in the…
