Answer:
force = 5.969 kN
Explanation:
given data
diameter of the hole D = 10 mm
thickness of sheet metal T = 1 mm
ultimate tensile strength = 190 MPa
solution
force is express as
force = ultimate tensile strength × Area ............1
and here area will be
area = π × D × T ................2
area = π × 10 × 1
area = 31.4159 mm²
so put value in equation 1 we get
force = 190 × 31.4159
force = 5969.02 N
force = 5.969 kN
Answer:
Explanation:
Power is defined as the rate of work done per unit time. Therefore, to obtain power, we divide work by time.

Answer:
False
Explanation :
lever is a rigid bar which turn around a pivot point, called a fulcrum. It is a simple machine and can be use to move a load (or do work). Effort is applied to one part of the lever and it pushes the load at another end. Therefore, the load is not the lever part of the fulcrum or pivot.
