Three timbers are placed on a surface in a way that their centers make an equilateral triangle. A constant force F= 1.0 N is then applied to one of them as shown below. What is the range of acceleration that would allow the timbers to remain in contact?
Suggested approach: take timbers as identical cylinders and identify all the forces on each of them. Draw free-body diagrams and apply Newton’s 2nd law. Solve the system of equations to find the inter-cylinder forces. At the moment the timbers lose contact the forces between them would become zero. Find the range of acceleration that keeps the forces nonzero. Write the final results in terms of g.

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
