Calculation Example – Friction ^{ Featured }
The friction coefficient is c1=0.2 between two bodies A,B. The friction coefficient is c2=0.18 between body B and the ground. If mass mA=0.5kgr and mB=1kgr , what is the minimum force P so that the two bodies start sliding?(we consider that there is no friction at the rope).
Calculation Example – Simple harmonic vibration part 2 ^{ Featured }
A single point with mass m is vibrating harmonically. The displacement x from point of balance is governed by the differential equation
Calculation Example – Simple harmonic vibration part1 ^{ Featured }
A single point with mass m is vibrating harmonically. The displacement x from point of balance is governed by the differential equation
Calculation Example – Critical load. ^{ Featured }
A solid rod has a diameter of 20 mm and is 600 mm long. It is made of a material that can be modeled by the stress–strain diagram shown in the figure below. If it is used as a pinsupported column, determine the critical load.
Calculation Example – Minimum allowable Diameter. ^{ Featured }
Determine the minimum diameter of the rod. The axial tensile force is P=10KN. The allowable stresses in tension and shear is 100MPa and 40MPa.
