Question

1. Numericals 1. A brick weighing 40 N having dimensions of 25 cm x 10 cm x 5 cm is kept on a table with its three different sides one by one. Calculate the pressure exerted in each of the three cases. 2. A man weighing 1500 N exerts a pressure of 105 N/m² on the ground. Calculate his area of contact with the ground. 3. A force of 20 N is applied on an object at a distance of 1 m from the pivoted point. Find the moment of force. 4. The hinge of a door is at a distance of 25 cm from the point of application of force. How much force must be applied so that it produces the moment of force of 4 Nm?
