What are the causes of damage to propellers?
Answer / Pradip Vashistha
Damage to propellers can be caused by several factors: 1) Collision with foreign objects, such as debris or submerged rocks. 2) Overloading, which can cause the propeller to exceed its design limits. 3) Poor maintenance, including worn-out bearings or improper pitch adjustments. 4) Cavitation, a phenomenon caused by rapid changes in pressure that can erode the propeller blades.

i want to know how a dg set run/works and what is strock and what difference in between two and four strock engine.
Assume a DC motor with the following parameters : Motor torque control = 0.0848 Nm/amperes Back EMF control = 0.0848 Volts/(rad/s) Armature resistance = 0.75  Moment of inertia = 0.00001696 kg/m2 With zero frictional load and taking a feed forward gain of 2, determine the motor response for a unit step function. please forwaded the answer to the below mail id thanks in advance Regrads, peer_kaba@yahoo.co.in
