FBD of the block can be given as
Therefore, we balance the
forces on the block in the x and y direction and calculate the
value of N.
Friction force can be given by
F=
N
The N calculated cannot be less than 18 N since it is a component of N itself

Consider the spring-mass system described by the equation my''+By+ky=0, where y denotes the distance from equilibrium. Suppose that mass is 3kg and that there is no friction. The spring is stretched by 0.1 m and then struck with a hammer so that y(0)=-0.1 and y'(0)=1, as a result, the mass begins to oscillate at the rate of 4 radians per second. a) What is the spring constant? Justify your answer by computing the homogeneous solution. b) What is the amplitude...

In the friction-free piston-cylinder assembly, initially there is a volume of 0.1 m³ air at 300 K temperature. The air is heated at a constant pressure of 300 kPa, at a constant piston velocity and a temperature of 600 K for 30 s. In this context, calculate the power to be given to the piston as [kW]. Show the process in the diagram T (° C) - v (m³ / kg).
