A circular disc bears against a frame structure and a wall, as shown inthe figure. All contacts with the disc are frictionless. The frame structurehas pin supports at A and B; there is an internal pin connection at C. If themaximum allowable reaction force at either of the pin supports is 8 kN, what isthe maximum allowable weight of the disk?

Propose a force standard different from the example of a stretched spring discussed in the text. Your standard must be capable of producing the sane force repeatedly.
In the design of a supermarket, there are to be several rampsconnecting different parts of the store. Customers will haveto push grocery carts up the ramps and it is desirable thatthis not be too difficult. The engineer has done a survey andfound that almost no one complains if the force requiredis no more than 18 N. Ignoring friction, at what maximumangle θ should the ramps be built, assuming a full 25-kg cart?
A 16-year-old employee working for Southern Virginia College's (SVC) bookstore during the summer months is helping prepare for Fall salesIt's a good way to make extra money, and the teen is saving for a car. Books from one supplier are shipped to the SVC bookstore in large crates equipped with rope handles on all sides. On one occasion, the teen momentarily pulled with a force of 669 N at an angle of 35.3above the horizontal to accelerate a 124-kg crate of books. The coefficient of friction between the crates and the vinyl floor is 0.588. Determine the acceleration experienced by the crate in m / (s ^ 2) Use the approximation g = 10; m / (s ^ 2)
A 7.1 kg mass on a frictionless inclined surfaceis connected to a 2.4 kg mass. The pulley ismassless and frictionless, and the connectingstring is massless and does not stretch. The2.4 kg mass is acted upon by an upward forceof 8 N, and thus has a downward accelerationof only 4.8 m/s^2.The acceleration of gravity is 9.8 m/s^2. What is the tension in the connecting string? Answer in units of N. What is the angle θ? Answer in units of ◦

You are climbing on a hill that is inclined at 22º with the horizontal and you wish tobuild a rope tow to pull yourself up. Ignoring friction, calculate the tension you needed on therope to give your body that has a mass of 55kg a 1.2m/s^2 acceleration. What if you are toconsider the friction of 150N, what is the value the tension and coefficient of friction?
