This project replaces an antiquated screw powered universal testing machine (UTM) with a modern UTM with a capacity of 400,000 lbs. in compression and 200,000 lbs. in tension. The UTM is hydraulically operated which offers more precise control that the mechanically operated screw type. This increased control makes it easier to control experiments and to improve accuracy when operating in the lower load ranges. The UTM is equipped with accessories which provide the civil and mechanical engineering departments the capability of testing concrete cylinders in compression, unthreaded rods and reinforcing bars, and flat bar specimens. A flat bed recorder is provided to make hard copy diagrams of stress versus strain for the materials tested. The new UTM is also used in demonstration in the Pre-Freshmen Engineering Program designed to minority high school students to the science and engineering fields. This award is being matched by an equal sum from the grantee.

该项目用400,000磅的现代化螺杆动力万能试验机(UTM)取代了陈旧的UTM。压缩和200,000磅。处于紧张状态。UTM是液压操作的，与机械操作的螺杆类型相比，提供了更精确的控制。这种增强的控制使控制实验变得更容易，并在较低负载范围内操作时提高精度。UTM配备了附件，为土木工程和机械工程部门提供了测试混凝土圆筒受压、无螺纹杆和钢筋以及扁钢试件的能力。提供了一台平板记录器，用于制作测试材料的应力-应变关系图的硬拷贝。新的UTM也被用于为少数族裔高中生设计的学前教育工程项目的示范。这笔奖金将由受赠人支付等额的奖金。
