Upgrading of the Universal Testing Machine for Under- graduate Civil and Mechanical Engineering

该项目用容量为40万磅的现代通用测试机取代了过时的螺旋动力通用测试机（UTM）。压缩和200000磅。在紧张。UTM采用液压操作，比机械操作的螺杆式控制更精确。这种增加的控制使得在较低负载范围内操作时更容易控制实验并提高精度。UTM配备了附件，为土木和机械工程部门提供了测试混凝土圆柱体受压、无螺纹杆和钢筋以及扁杆试件的能力。提供了一个平板记录仪，以制作测试材料的应力与应变的硬拷贝图。新UTM还被用于为少数民族高中理工科学生设计的大一前工程课程的示范。这笔奖金将由受资助者提供等额的奖金。

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.
