Executive Summary
The objective of the lab was to comprehend and study the impact of water jets on
several different target shapes. Applying the conservation of momentum, the average
flow rate and velocity are found. From that point, the theoretical resul
Objective:
The meaning of viscosity is the measure of a fluid's resistance to flow. Therefore it is required
for engineers to have the knowledge on viscosity and the value of it because it can have a huge
effect on engineering projects and assignments or

1. The 2-lbf block is released from rest at A and slides down along the smooth cylindrical
surface. If the attached spring has a stiffness k = 2 lbf/ft, determine its unstretched length so
that it does not allow the block to leave
Assignment 3 : solutions
1. Determine the time needed to pull the cord at B down 4 ft starting from rest when a force of
10 lb is applied to the cord. Block A weighs 20 lb. Neglect the mass of the pulleys and cords.
2. The sliders A and B are connected by
