A 3-phase stepping motor is to be used to drive a linear axis for a robot. The motor output shaft will be connected to a screw t
hread with a screw pitch of 1 mm. We want to be able to have a spatial control of at least 0.05 mm. a. How many poles should the motor have? b.How many pulses are needed from the controller every second to move the linear axis at a rate of 90 mm/sec?

At equilibrium, the sum of clockwise and anticlockwise moments about a point is zero
The mass of that balances the system is kg
The normal reaction force at the fulcrum is <u>5,804.25 N</u>
Rason:
The mass of the stick = 150.0 g
Mass m₁ on the left = 50.0 g, location = 30 cm to the left of m₂
Mass m₂ on the left = 75.0 g, location = 40 cm to the left of the fulcrum
Mass m₃ on the right of the fulcrum. location = 30 cm to the right of the fulcrum
Required:
To find the mass of m₃
Solution:
Taking moment about the fulcrum, we have;
50 × (30 + 40) + 75 × (40) + 150 × 20 = m₃ × 30
9,500 = m₃×30
The mass of that balances the system when it is attached at the right end of the stick, m₃ = kg
Normal reaction at the fulcrum = (50 + 75 + 150 + ) × 9.81 = 5804.25
The normal reaction at the fulcrum is 5,804.25 N
