Block on an incline and frictional force

05/12/2015That's not a valid equation. FA (which is horizontal) and the friction force (which acts along the slope) do not act along the same direction. The force due to friction is obtained from the normal force and the friction coefficient. The normal force is made up of two contributions: one due to a component of the block's gravitational weight, the other due to a component of the force FA. So FA

Rod mills, how they function

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the

MR Imaging of Temporomandibular Joint Dysfunction: A

01/05/2006Disk injuries are the most common cause of TMJ dysfunction. MR imaging is currently the standard imaging technique for diagnosing disk injuries, which can manifest as intrinsic disk lesions (eg, changes in shape and signal intensity) or disk displacement (, 22). In the early stages of internal derangement, the disk retains its normal shape. Over time, however, the displaced disk is deformed
