In the vector form, it may be written as follows [3]: (2.2)F→=V→|V→|μ|W→|, where V→ is the sliding velocity, and the ratio V→/|V→| is nonlinear, which results in some static frictional problems. Dynamic friction is employed to resolve this problem. In general, the ...

The equation for the formula of Force can be expressed in the form given below: F = ma Where, m = mass a = acceleration It is formulated in Newton (N) or Kgm/s2. Acceleration “a” is given by, a = v/t Where, v = velocity t = time taken So Force can be defined as F = ...

(9.6). If the problem is of two dimensions, namely, all the forces lie in the Oxy plane, only the first two columns of F and R need to be specified. resultant (F) only computes the resultant force. [F_sum, M_sum] = resultant (F, R) returns the resultant force in a vector F...
