4. Rolling. A series of cold rolling operations is to be used to reduce the thickness of a plate from 80 mm to 30 mm. Roll diameter is 800 mm, friction coefficient between rolls and workpiece is 0.15, assume the draft is to be equal on each pass: (1) Minimum number of passes; (2) Draft for each pass.
Q3. ( 25 points) A rolling mill used to reduce a sheet strip by 3 mm in thickness. The sheet has 2.5 cm thickness and 30 cm in width. The rolling speed is 0.83 rev/sec. The sheet material flow stress is given by a = 275€0.15. A compression test was conducted to find the coefficient of friction and revealed that the coefficient of friction is 0.12. Check if the friction is adequate for the rolling operation. If it is calculate...
In a manufacturing process, a large, cylindrical roller is used to flatten material fed beneath it. The diameter of the roller is 9.00 m, and, while being driven into rotation around a fixed axis, its angular position is expressed as theta = 2.90t^22 - 0.650t^3 where 6 is in radians and t is in seconds. Find the maximum angular speed of the roller. What is the maximum tangential speed of a point on the rim of the roller? At what...
In a manufacturing process, a large, cylindrical roller is used to flatten material fed beneath it. The diameter of the roller is 4.00 m, and, while being driven into rotation around a fixed axis, its angular position is expressed as θ = 2.30t2 − 0.850t3 where θ is in radians and t is in seconds. (a) Find the maximum angular speed of the roller. rad/s (b) What is the maximum tangential speed of a point on the rim of the...

Vhat position shou ariatric patient be placed to aid pulmonary function during the immediat 4. A bariatric patient has recently undergone a gastric bypass procedure and complains of periumbilical pain. What complication is the patient possibly experiencing and what type of surgical procedure will be performed to repair it? . What device is frequently used during...
With effective resource planning, organizations can reduce inventory and service costs, improve efficiencies, and establish methods for continuous improvement. Depending upon the type of resource, there is a different type of planning that must take place. This can include material requirements planning (MRP), capacity requirements planning (CRP), enterprise resource planning (ERP), customer relationship management (CRM), supply chain management (SCM), or product lifecycle management (PLM). Research two specific types of resource planning. Based on your research, explain whether or not you...

As part of the ride, a roller coaster crests a hill that can be approximated as a circle with a radius of 30.0 meters. How fast would the coaster need to be traveling at the top of the hill if the safety harness in the car needed to exert a force that held a 80.0-kg rider down and had a magnitude of 250 N?
