To transport a series of bundles of shingles A to a roof, a contractor uses a motor-driven lift consisting of a horizontal platform BC which rides on rails attached to the sides of a ladder. The lift starts from rest and initially moves with a constant acceleration a(1) as shown. Knowing that the coefficient of static friction between a bundle of shingles and the horizontal platform is 0.25 , determine the largest allowable acceleration a(1) , if the bundle i, NOT to slide on the platform. (Fig 2).

Problem 2:
To transport a series of bundles of shingles A to a roof, a contractor
uses a motor-driven lift consisting of a horizontal platform BC which
rides on rails attached to the sides of a ladder.
The lift starts from rest and initially moves with a constant
acceleration a(1) as shown.
Knowing that the coefficient of static friction between a bundle of
shingles and the horizontal platform is 0.25 , determine the largest
allowable acceleration a(1) , if the bundle i, NOT to slide on the
platform. (Fig 2).
