(i) Consider the linear viscous dashpot shown in the figure below. If the piston of the dashpot is moved with a velocity of 2 cm/s towards the left, which of the following statements is true? WWW a. The dashpot exerts a constant force on the support acting towards the right b. The dashpot exerts a constant force on the support acting towards the left c. The dashpot exerts a linearly increasing force on the support always acting to- wards the right d. The dashpot exerts a linearly increasing force on the support always acting to wards the left e. The provided information is insufficient to comment on the nature of force ex- erted by the dashpot on the support (ii) Which of the following statements regarding the response of the SDOF system shown below to support excitation is always true?
ug(t) >' (t) с m E w k a. The net force acting on the block is zero b. The force in the spring is zero c. The force in the dashpot is zero d. The sum of the forces in the spring and dashpot is zero e. The force exerted on the support is zero f. All of the above & None of the above
