Answer:
Velocity
Explanation:
The slope of a position-time graph gives velocity of a moving object.
Answer:
The moment is 81.102 k N-m in clockwise.
Explanation:
Given that,
Force = 260 N
Side = 580 mm
Distance h = 370 mm
According to figure,
Position of each point



We need to calculate the position vector of AB


We need to calculate the unit vector along AB


We need to calculate the force acting along the edge


We need to calculate the net moment

Put the value into the formula




Put the value into the formula


Negative sign shows the moment is in clockwise.
Hence, The moment is 81.102 k N-m in clockwise.
