Discussion on Correction Checking of Two-beam Bolt Connection

A strength check is required to ensure that the maximum tensile force, Nmax, acting on the high-strength bolt due to tension does not exceed a specified limit. This limit is defined as . Since the flange joint is located away from the end beam support, the flange plate experiences a bending moment, which in turn causes the bolts to be pulled. It is assumed that the flange farthest from the neutral axis will experience the highest tensile force, and similarly, the bolt located farthest from the axis will endure the maximum tension. The tensile force can be calculated using the following formula: Nmax = MP * (ln - l1)^2 / [ (L2 - l1)^2 + (l3 - l1)^2 ]. Here, MP represents the bending moment acting on the flange. The bending moment MP can be determined by the equation: MP = Fa * #a, where Fa is the applied force and #a is the lever arm. To calculate Fa, the following expression is used: Fa = P1 * LK - aLK + P2 * LK - a - KTLK + 7G2. Finally, the allowable tensile force is given by = S / , where S is the cross-sectional area of the bolt. This calculation ensures that the bolt remains within its safe working limits under the applied load.

5 Bars Led Grow Light

5 bars LED Grow Light is a kind of lamp that provides light for plants. It usually consists of five light bulbs, each representing a claw, which can provide plenty of light and lighting effects.

The use of the 5 bars led grow lights can be described according to the following aspects:

1. Light time: According to the needs of plants, the use time of 5 bars growth lights can be adjusted according to different stages and types. Generally speaking, the time that plants need light is generally about 10-12 hours.

2. Light intensity: The light intensity of the 5 bars grow light can be adjusted according to different plant types and growth stages. For plants that need stronger light, the lamps can be placed in a closer position to provide stronger light.

3. Lighting range: The lighting range of the 5 bars indoor grow light depends on the design and installation position of the lamp. In general, the lamp should be able to cover the entire growing area of the plant to ensure that the plant can fully receive the light.

4. Use environment: 5 bars plant lights can be used in both indoor and outdoor environments, but they are usually more suitable for indoor use. In the indoor environment, the lamps can be placed in different positions as needed to meet the light needs of the plants.

In general, the use of the 5 bars plant grow light should be adjusted according to the needs of the plant and the growth environment. Through reasonable light time, light intensity and lighting range, it can provide suitable light conditions for plant growth and promote the growth and development of plants.
