The roof load is transmitted to the truss first. It is then transmitted to the joints. This transmission of the force or the load from trusses to the joints is achieved by the purlins. Thus the distribution of the load.

Load transmission in a roof supporting truss:
A roof supporting truss is a structural framework designed to bear the weight of the roof and transfer it to the supporting walls. The load is transmitted through the truss system to the purlins and then to the joints. The correct option is A, which states that the load is first transmitted to the truss and then to the joints through purlins. Let's understand this in detail:
Load transmission process:
The load on the roof is transferred to the truss system through the roofing material.
The truss system is designed to distribute the load evenly across the entire structure, reducing the stress on individual members.
The load is first transferred to the truss members, which are the primary load-bearing components of the system.
From the truss members, the load is transmitted to the purlins, which are secondary load-bearing components.
The purlins are horizontal beams that run perpendicular to the truss members and provide support for the roofing material.
Finally, the load is transmitted to the joints, which are the connection points between the truss members and the purlins.
The joints are designed to transfer the load from the truss members to the purlins without causing any damage to the structure.
Importance of load transmission:
Proper load transmission is critical to the structural integrity of the roof supporting truss. If the load is not distributed evenly, it can cause stress concentrations in individual members, leading to failure of the structure. Therefore, it is essential to design the truss system to ensure even load distribution and proper load transmission.
Conclusion:
In conclusion, the load in a roof supporting truss is transmitted from the truss members to the purlins and then to the joints. The correct option is A, which states that the load is first transmitted to the truss and then to the joints through purlins. Proper load transmission is essential to ensure the structural integrity of the truss system.
