Two projectiles βAβ and βBβ are thrown with same speed but at angle of 40 degree and 50 degree with the horizontal. The horizontal range of βAβ will be:
A rigid uniform bar of length 2.4 m is pivoted horizontally at its mid-point, weights are hung from two points
of the bar as shown in diagram. To maintain horizontal equilibrium, a couple is applied to the bar:
What is the torque and the direction of couple?
In the absence of air resistance, a stone is thrown from P and follows a parabolic path in which the highest
point reached is T. The vertical component of acceleration of stone is:
Two 8 N forces act on each end of the beam of length 0.60m. Two forces are parallel and acting opposite to
each other, the angle between the force and beam is 60o
, what is the torque of the couple exerted on the
beam:
