Wrong. A cloth covering would have little to no effect in reducing the impact in this case, even though there is no cloth covering on the fire extinguisher. Do you think being struck with a bare padlock would be harder than being struck with a padlock in a sock?Yes, the degree to which an object can deflect from the vector of collision has a direct effect on the amount of force transferred to the object it collides with. A projectile with a hard exterior surface and rough edges is less likely to deflect at the point of impact that a smoother hard object covered by a softer displaceable exterior. And then, in addition, there is the cushioning effect of whatever the covering is.
Basic physics. A soft covering operates in the same way as grease. That's why boxers put vaseline on the faces. To reduce the force of punches that are landed.
And boxers apply vaseline to reduce the risk of cuts from the friction of the gloves, not because of some imaginary cushioning effect.
And you want to be taken seriously.
