Weight of the barbell W = 200 Ndistance of the joint is r = 40 cm = 0.4 mtorque created by the weight at the joint is τ = F*r = 200 N*0.4 m = 80 N.mat equilibrium condition , Στ = force*distance - 80 N.m = 0 F'*0.4 - 80 N.m = 0 F'*0.4 = 80 force F' = 200 N
Maximum torque.
T=F.r
r is measured from point of turning, which is the hinge. r is maximum when the handle is at the free edge.
Gravity has an effect on weight, but not on mass. The mass of the object will be the same on both planets. (choice-C)
Answer: B
Explanation: A sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball (viz., analogous to the circular objects in two dimensions, where a "circle" circumscribes its "disk"). Like a circle in a two-dimensional space, a sphere is defined mathematically ... This distance r is the radius of the ball, which is made up from all points.
