Final answer:
An overhanging rake is more difficult to support than an overhanging eave due to differences in structure, load distribution, and leverage. The longer and steeper slope of a rake increases the forces acting on it, making it more challenging to support.
Step-by-step explanation:
An overhanging rake is more difficult to support than an overhanging eave because of the differences in their structures and load distributions. A rake is the sloping edge of a roof that extends beyond the wall, while an eave is the horizontal projection of the roof beyond the wall. The rake is typically longer and has a higher angle of inclination, which increases the forces acting on it, making it more challenging to support.
When a rake is overhanging, it creates a larger lever arm, causing the forces exerted on it to be greater compared to an eave. This additional leverage makes it harder for the structure to resist the bending moments and prevent collapse. The design and construction of the support system need to account for these factors to ensure the stability and safety of the roof.
