✦ Synopsis

We developed an online Free Body Diagram (FBD) Assistant that allows students to construct 2-D FBDs and to receive constructive feedback for a wide range of practice problems. The system's architecture allows for interoperability between learning management systems and interactive student simulations designed to improve both learning and assessment. The system gathers useful information about students' decision processes as they construct FBDs. This information can be used with a diagnostic module we have developed to reliably, and dynamically, construct appropriate feedback that is specific to the diagram submitted by the student. Students use this asynchronous system to gain practice in constructing FBDs at their own pace, and their records can be analyzed to indicate progress over time.

## Abstract This study is concerned with the conditions for the initiation of various modes of response of a free‐standing rigid body, initially at rest, placed on a frictional horizontal base which undergoes earthquake‐like accelerations in both the horizontal and vertical directions. These condit
