This research article examines the design, development, and performance analysis of a Tensile Creep Test Apparatus (CTA) for identifying the creep characteristics of materials like Nylon, UPVC, lead, and MDPE under sustained loads. The CTA employs a spring mechanism to maintain a constant load on the specimen, enhancing experimental precision. The apparatus consists of three sections: the first allows manual load application, transferring force to the second section with springs for consistent loading, and the third holds the specimen between flanges for uniform force dispersion. Load data are collected via a load cell in this section, and extension measurements are taken using a manual scale near the flange. The apparatus can apply loads up to 1.1 kN and accommodates dog bone-shaped specimens. A 120-hour creep test was conducted under varying stress levels at ambient temperatures between 29 oC and 33 oC. Results showed a progressive increase in specimen extension and creep rate over time, correlating with higher loads at constant temperatures. The observed creep curves closely matched empirical data obtained through stress relaxation methods, demonstrating the apparatus's utility and reliability in characterizing material creep behavior.

Since the use of aluminum products in various applications continues to increase, the use of aluminum raw materials has further increased, leading to shortages of aluminum raw materials. Recycled aluminum waste can reduce the use of aluminum raw materials as soft drink cans are a good source of aluminum to meet demand. Material testing is the main and crucial activity which is carried out whenever a material is developed and is to be used in a specific application. Such testing results whether the tested material is laid under the designed parameters or not. Concerning such causes, the mechanical properties were tested by different material testing equipment including universal testing machine, creep testing, and fatigue testing. Furthermore, the combined bending and torsion machine was also developed which can perform both bending and torsional tests for small researched or study-based materials or specimens to fulfill the need of the laboratory. However accurate operation of the machine for the tested results are compared with theoretical calculations & simulated results and it was found that the results satisfied acceptable precision error percentages.

In agriculture, automation of spraying has boosted farm productivity. As a result, the labor issue has been resolved. However, the situation is different in a nation like Pakistan. Automation in the agricultural sector is challenging in these arid regions because the most Pakistani farmers are struggling financially. Therefore, the wide use of the manually operated sprayer is still common in majority of the areas of Pakistan. Due to its affordability, design, and versatility, manually lever driven backpack sprayers are much sought after by small-scale farmers. Two types of sprays are utilized in Pakistani farms: fuel-operated pumps and hand-operated ones. The primary disadvantage of a hand-operated spray pump is that its user cannot use it continuously for longer than five to six hours. Due to fatigue, long working hours are impossible without integration of any other energy, but a gasoline-operated spray pump needs fuel, which is costly and difficult to find in remote areas. Therefore, the work represents the integration of renewable energy (solar power) and a manually operated mechanism to achieve sustainability with increased efficiency and reduced human efforts.  It is observed from the results that around 2.5 times increased discharge was achieved, and time is reduced by 2.5 times. The proposed idea drives a solar powered multi-nozzle with pump, which sprays pesticide uniformly, along with environmental benefits. In result, pesticide sprayer reduces farmer fatigue and sprays at its highest pace in the shortest amount of time without requiring fuel.
