Preload ensures that enough pressure is placed on the bearing, so as to keep the shaft from moving around while preventing the bearing from running hot.
<h3>What is preload?</h3>
Preload can be defined as the load (amount of force) that is generated from an axial interference within a bearing, which causes an elastic deformation between the rolling elements and raceway.
In Engineering, preload is a technique which ensures that enough pressure is placed on the bearing, so as to keep the shaft from moving around while preventing the bearing from running hot and failing.

Answer:
The main reason for the existence of an organization is to generate profits, but it is increasingly required through the legal and social obligation that companies are not only profitable entities, but promoters of the well-being and development of society.
Therefore, the balance between the resources for its financial goals and objectives and social responsibility goals will be achieved through the adoption of processes that include environmental and social management as an integral and important part of the general administration, which is not an exclusion for generation profitability, but a tool that will help achieve organizational goals and objectives.
Environmental and social management through certifications, programs and management systems, provides policies and procedures that help companies reduce their costs, eliminate waste, improve productivity, generate stakeholder satisfaction and several other benefits that promote continuous improvement and consequently the improvement in the company's positioning in the market.
Systems Engineering (SE) is the engineering discipline that focuses on integrating all the key elements of a system into one overall system and managing it throughout its lifecycle from cradle to grave. It’s focuses on the overall development process of a system that is based on established processes, documented needs and traceable communications or interaction among the customers, users, engineers, and other stakeholders. The overall goal of SE is to develop and design a system that meets a specific set of requirements (needs) in the guidelines established by the Program Manager (PM). A systems engineer in the DoD will develop, design, allocate, and manage user and system level requirements (see Requirements Development), lead the development of the system architecture, evaluate design tradeoffs, balance technical risk between systems, define and assess interfaces, provide oversight of verification and validation activities, as well as many other tasks throughout the course of a program. In short, SE is the technical discipline that glues all the pieces together to make the end product.
Answer:
Explanation:
The 3-bit Synchronous binary up counter comprises of, three T flip-flops & one 2-input AND gate. All these flip-flops are negative edge triggered and the outputs of flip-flops change affect synchronously. The T inputs of first, second and third flip-flops are 1, Q0 & Q1Q0 respectively.
Please refer to attachment for the detailed image if the 3-bit synchronous counter using D flip-flops. The counter will count when the enable (EN) is zero and hold when enable is one. The counter has an output, Z, which is high when the count is 100.
Answer:
The period is 0.628s
Explanation:
As the system mass-spring is in simple harmonic motion, the period is given by the equation:
where m is the mass of 2kg and k is the spring constant
Replacing the values in the equation, we have:
And finally we find the value of the period, that is:
