A 10cm long 2cm wide wooden wedge is pushed into asoftwood block calculat
A. the velocity ratio of the wedge
B. the load on the soft wood if the effort applied is 30m(assuming the wedge is 100% efficient
To calculate the velocity ratio of the wedge, you need to know the length and width of the wedge. The velocity ratio is defined as the ratio of the distance the effort moves to the distance the load moves.
In this case, the distance the effort moves is the width of the wedge, which is 2 cm. The distance the load moves is the length of the wedge, which is 10 cm. Therefore, the velocity ratio (VR) can be calculated using the formula:
VR = Distance effort moves / Distance load moves
VR = 2 cm / 10 cm
VR = 0.2
So, the velocity ratio of the wedge is 0.2.
To calculate the load on the softwood block, you need to know the effort applied and the efficiency of the wedge. The load can be calculated using the formula:
Load = (Effort x VR) / Efficiency
In this case, the effort applied is given as 30 m. The velocity ratio of the wedge is 0.2. And assuming the wedge is 100% efficient, the efficiency is 1.
Load = (30 m x 0.2) / 1
Load = 6 m
Therefore, the load on the softwood block is 6 m if the effort applied is 30 m and assuming the wedge is 100% efficient.
