The engineered concrete slab is a fundamental structure in construction with its mechanical properties influenced by the rebar placement, curing process, and the ratios of its primary components aggregate, cement, and sand. This study investigates how variations in rebar placement, concrete composition and curing methods effect the flexural strength of the sample. In ENGR 30014, 18 engineering teams produced their best sample of concrete with different ratios, rebar patterns, and different types of curing. The results provide insights into optimizing the concrete ratios, rebar placement, and methods for curing and their effect on flexural strength.

The goal of this research was to enable information transmission through light using a Phase Light Modulation (PLM) module to decode and display encrypted information. We conducted a literature review and set up an evaluation module capable of sending encrypted messages and transmitting data without the need for optical cables. Our setup includes a laser light source, a beam expander, a Digital Micromirror Device (DMD) controlled by an electronic control board, and a laptop running the software GUI provided by Texas Instruments. We conducted various experiments with these components to optimize the design and explore potential applications. Our findings highlight the potential of this technology for future data transmission and optical devices.

Winter can turn plumbing into a battlefield, with frozen pipes bursting and their joints failing under pressure. In this study, 18 teams of student researchers will face off in a school lab to test three common plumbing materials, copper, PVC, and PEX studying their joining techniques; soldering, solvent welding, and crimping against freezing conditions.
Over two weeks, we will subject a series of pipe assemblies into brutal freeze to thaw cycles, mimicking harsh winter weather, to see which ones crack, leak, or stand strong. By analyzing failure rates and durability, we aim to uncover the ultimate cold weather champion and share practical insights for homeowners and plumbers. Get ready our pipes are about to feel the chill!

This design proposal outlines the development of a bearing installation and proof-load testing tool intended to streamline and enhance the bearing installation process for Aero Components. The project focuses on creating an efficient and innovative solution using hydraulic press technology, with particular attention to the requirements of staking and swaging methods for securing bearings. The proposed design utilizes the HSP-30M Baileigh Hydraulic Press, which will be customized to meet specific operational needs, such as accommodating bearing diameters up to 3 inches and applying precise deformation forces. Key features include the development of a versatile attachment system, safety enhancements, and a digital feedback mechanism to monitor and control the hydraulic pressure during both installation and testing phases. The project aims to meet performance criteria, including visual inspection standards and proof-load testing requirements, ensuring the tool’s effectiveness and repeatability. Through a comprehensive testing regimen, the system’s reliability will be validated, with results documented to confirm the tool’s ability to perform under operation conditions. The proposal also includes a detailed project timeline, budget projections, and cost-management strategies, ensuring the project will be completed on time and within budget. The ultimate goal is to provide Aero Components with a tailored solution that optimizes bearing installation efficiency while maintaining high standards of safety, precision, and performance.

The growing environmental concern surrounding plastic waste has prompted the exploration of innovative recycling and reusing methods. This research investigates the potential of utilizing high-density polyethylene (HDPE) and low-density polyethylene (LDPE) plastic waste to create sustainable bricks. Building on the work of Gjenge Makers, who have developed pavers from recycled plastic and sand, this study aims to evaluate the strength, durability, and environmental impact of plastic-sand composites and assess their viability as a substitute for conventional construction materials.
