Question 1
In a free body diagram, which information is correct?
Question 2
The figure shows a pin-jointed plane truss loaded at the point M by hanging a mass of 100 kg. The member LN of the truss is subjected to a load of
Question 3
A block of mass M is released from point P on a rough inclined plane with inclination angle θ, shown in the figure below. The co – efficient of friction is μ. If μ < tan θ, then the time taken by the block to reach another point Q on the inclined plane, where PQ = s, is
Question 4
An inextensible massless string goes over a frictionless pulley. Two weights of 100 N and 200 N are attached to the two ends of the string. The weights are released from rest, ad start moving due to gravity. The tension in the string (in N) is ____
Question 5
Two books of mass 1 kg each are kept on a table, one over the other. The coefficient of friction on every pair of contacting surfaces is 0.3. the lower book is pulled with a horizontal force F. the minimum value of F for which slip occurs between the two books is
Question 6
Two cylinders C & D rest in a horizontal channel as shown in figure. The cylinder C has a weight of 1200 N and radius of 8 cm. The cylinder D has a weight of 600 N and radius of 6 cm. The channel is 20 cm wide at the bottom with one side vertical. The other side is at an angle 60o with the horizontal. Find the reactions at points P & Q (in N)
