Abstract: A system and method for calculating task times for a project. A project estimating system is disclosed that allocates time to a list of tasks, comprising: a system for determining a total project time to complete a project; and a time allocation system that generates a task time for each task based on the total project time and an estimating factor associated with each task, wherein the time allocation system includes an iterative algorithm that iteratively calculates an adjustment factor to be applied to each task. Finally, the calculated adjustment factor can be compared against preset levels and provide an indication of project risk and the likelihood that the project will complete on time.

Abstract: A torque-transmitting chuck comprising an interior member having a longitudinal axis and exterior circumferentially-spaced, longitudinally-extending camming surfaces. A generally axially-extending, circular in cross-section roller engages each of the camming surfaces. Each roller is arranged to engage the interior of a hollow core and move radially outwardly relative to the interior member in response to movement of the roller circumferentially of the interior member. The chuck is characterized in that each of the rollers includes an axially-extending center rod and a thick surrounding layer of resilient material the outer circumferential surface of which contacts the camming surfaces and core. The layer has a hardness in the range of 30 to 90 durometer and a radial thickness of not less than about 1/8 inch.
